Program 1

Word is the Key

Word is the Key 💖 (Link to this question)

(TCS Ninja – Aug 2019 Slot 1)

One programming language has the following keywords that cannot be used as identifiers:

break, case, continue, default, defer, else, for, func, goto, if, map, range, return, struct, type, var

Write a program to find if the given word is a keyword or not

Test cases

Case 1

Input – defer
Expected Output – defer is a keyword

Case 2

Input – While
Expected Output – while is not a keyword

C Program

#include<stdio.h>
#include<string.h>

int main(){
    
    char str[16][10] = {"break", "case", "continue", "default", "defer", "else","for", 
    "func", "goto", "if", "map", "range", "return", "struct", "type", "var"};
    
    char input[20];
    
    int flag = 0;
    scanf("%s",input);
    
    for(int i = 0; i<16;i++){
        if(strcmp(input,str[i]) == 0){
            flag = 1;
            break;
        }
    }
    
    if(flag==1){
        printf("%s is a keyword",input);
    }
    else{
        printf("%s is not a keyword",input);
    }

Oddly Even

The Oddly even 💖 (Link to this question)

(TCS Ninja – Aug 2019 Slot 3)

Problem

Given a maximum of 100 digit numbers as input, find the difference between the sum of odd and even position digits

Test Cases

Case 1

Input: 4567
Expected Output: 2

Explanation : Odd positions are 4 and 6 as they are pos: 1 and pos: 3, both have sum 10. Similarly, 5 and 7 are at even positions pos: 2 and pos: 4 with sum 12. Thus, difference is 12 – 10 = 2

Case 2

Input: 5476
Expected Output: 2

Case 3

Input: 9834698765123
Expected Output: 1

The Sholka Problem 💖 (Link to this question)

(TCS Ninja – Aug 2019 Slot 4)

Our hoary culture had several great persons since time immemorial and king vikramaditya’s nava ratnas (nine gems) belongs to this ilk. They are named in the following shloka:

Among these, Varahamihira was an astrologer of eminence and his book Brihat Jataak is recokened as the ultimate authority in astrology.

He was once talking with Amarasimha,another gem among the nava ratnas and the author of Sanskrit thesaurus, Amarakosha.

Amarasimha wanted to know the final position of a person, who starts from the origin 0 0 and travels per following scheme.

Scheme

He first turns and travels 10 units of distance
His second turn is upward for 20 units
Third turn is to the left for 30 units
Fourth turn is the downward for 40 units
Fifth turn is to the right(again) for 50 units

… And thus he travels, every time increasing the travel distance by 10 units.

Test Cases

Case 1

Input : 3
Expected Output :-20 20

Case 2

Input: 4
Expected Output: -20 -20

Case 3

   else
      cout<<year<<" is not a leap year";
   return 0; 
}

Output

2016 is a leap year

In the above program, if a year is divisible by 4 and not divisible by 100, then it is a leap year. Also, if a year is divisible by 400, it is a leap year.

This is demonstrated by the following code snippet.

if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0))
   cout<<year<<" is a leap year";
else
   cout<<year<<" is not a leap year";

The program to check if a year is leap year or not can also be written using nested if statements. This is given as follows −

Java

import java.util.Scanner;
public class Demo {

    public static void main(String[] args) {

    	int year;
    	Scanner scan = new Scanner(System.in);
    	System.out.println("Enter any Year:");
    	year = scan.nextInt();
    	scan.close();
        boolean isLeap = false;

        if(year % 4 == 0)
        {
            if( year % 100 == 0)
            {
                if ( year % 400 == 0)
                    isLeap = true;
                else
                    isLeap = false;
            }
            else
                isLeap = true;
        }
        else {
            isLeap = false;
        }

        if(isLeap==true)
            System.out.println(year + " is a Leap Year.");
        else
            System.out.println(year + " is not a Leap Year.");
    }
}

Perl

# perl Script
# leap year
print "Enter Year: ";
$year=;
# condition to check for leap year
  if( (0 == $year % 4) && (0 != $year % 100) || (0 == $year % 400) )
    {
        print "Leap year";
    }
    else
    {
        print "Not a leap year";
    }

Output

Question. Find the nth term of the series.

1, 1, 2, 3, 4, 9, 8, 27, 16, 81, 32, 243,64, 729, 128, 2187 ….

This series is a mixture of 2 series – all the odd terms in this series form a geometric series and all the even terms form yet another geometric series. Write a program to find the Nth term in the series.

The value N in a positive integer that should be read from STDIN.
The Nth term that is calculated by the program should be written to STDOUT.
Other than value of n th term,no other character / string or message should be written to STDOUT.
For example , if N=16, the 16th term in the series is 2187, so only value 2187 should be printed to STDOUT.

You can assume that N will not exceed 30.

Test Case 1

Input- 16

Test Case 2

Input- 13
Expected Output – 64

(TCS Ninja – Dec 2018 Slot 2)

Explanation

1, 1, 2, 3, 4, 9, 8, 27, 16, 81, 32, 243,64, 729, 128, 2187 can represented as :

2⁽⁰⁾, 3⁽⁰⁾,2⁽¹⁾, 3⁽¹⁾,2⁽²⁾, 3⁽²⁾,2⁽³⁾, 3⁽³⁾,2⁽⁴⁾, 3⁽⁴⁾,2⁽⁵⁾, 3⁽⁵⁾,2⁽⁶⁾, 3⁽⁶⁾….

There are two consecutive sub GP’s at even and odd positions

(GP-1) At Odd Positions (Powers of 2) – 1, 2, 4, 8, 16, 32, 64, 128
(GP-2) At Even Positions (Powers of 3) – 1, 3, 9, 27, 81, 243, 729, 2187

Clearly, for calculating Nth position value

If N is Even, Find (N/2) position in sub GP – 2
If N is Odd, Find (N/2 + 1) position in sub GP – 1

1. The program will recieve 3 English words inputs from STDIN

These three words will be read one at a time, in three separate line
The first word should be changed like all vowels should be replaced by *
The second word should be changed like all consonants should be replaced by @
The third word should be changed like all char should be converted to upper case
Then concatenate the three words and print them

Other than these concatenated word, no other characters/string should or message should be written to STDOUT

For example if you print how are you then output should be h*[email protected]

You can assume that input of each word will not exceed more than 5 chars

Question 1:

Finding GCD of two numbers

// C program to calculate GCD of two numbers 
#include <stdio.h>
// The code used a recursive function to return gcd of p and q 
 int gcd(int p, int q) 
 { 

   // checking divisibility by 0 
    if (p == 0) 
       return q; 
  
    if (q == 0) 
       return p; 

    // base case 
    if (p == q) 
      return p; 
    
   // p is greater  
    if (p > q) 
        return gcd(p-q, q);   

    else
        return gcd(p, q-p); 
 } 

// Driver program to test above function

{ 
    int p = 98, q = 56; 
    printf("GCD of %d and %d is %d ", p, q, gcd(p, q)); 
    return 0; 
}

Question 2

         //num/=10; 
          num = num / 10 ;
         //base*=2;
          base = base * 2;
      }
     //display binary number

Question 4

Write a C program to find the area of a circle with radius provided.
The value of radius positive integer passed to the program as the first command line parameter. Write the output to stdout formatted as a floating point number rounded to EXACTLY 2 decimal precision WITHOUT any other additional text.
Scientific format(such as 1.00E+5) should NOT be used while printing the output.
You may assume that the inputs will be such that the output will not exceed the largest possible real number that can be stored in a float type variable.

It is highly advisable to go through Command Line Arguments Post before even looking at the code. Please study this for TCS and come back to this post later.

#include<stdio.h>
int main()
{

//for initialization of radius and area in a float datatype
float radius,area,pi=3.14;

// for use user input

printf("Enter the Radius of a Circle : ");
scanf("%f",&radius);

//formula of area of circle

area = pi*radius*radius;

printf("Area of Circle is: %f",area);
return 0;
}

Question 5

      printf("Enter Year for find leap year or not : ");
     scanf("%d",&year);

       //we use this statement for check leap year 
     if(((year%4==0)&&(year%100!=0)) || (year%400==0))
          printf("%d is a Leap Year",year);

      //not leap year

      printf("enter a limit of series \n");
      scanf( "%d",&limit);

      printf("Fibonacci series %d %d ",n1,n2);

      //To use this loop for given length
      for(i=2;i<limit;i++)
      {
           //n1 and n2 sum  store in new variable n3
           n3=n1+n2;   
           n1=n2;
           n2=n3;

Hi,

Command Line will not be used as a coding language in TCS Ninja Test. However, you need to learn command line programming, it is very important that you do. As 1 MCQ question in programming Logic section will be asked from command line programming basics.

Thank you sir. The questions that you gave above was repeated in my Bsc for tcs that happened on July 5, 2019. Thank you so much.

It was exact same I even knew the code as I did it a day before from your website. I hope that I clear my interview as well
