IBM Coding Questions and Answers

1. Write a program to find HCF of two numbers by without using recursion.

Input format:

The first line contains any 2 positive numbers separated by space.

Output format:

Print the HCF of given two numbers.

Sample Input:

70 15

Sample Output:

5

 

Run 
#include<iostream>
int gcd(int,int);
int main()
{
    int m,n,ans;
    scanf("%d",&m);
    scanf("%d",&n);
    while(m!=n)
    {
        if(m>n)
        {
            m=m-n;
        }
        else
        {
            n=n-m;
        }
    }
    printf("%d",m);
    return 0;
}

Q2. Consider a string, S, that is a series of characters, each followed by its frequency as an integer. The string is not compressed correctly, so there may be multiple occurrences of the same character. A properly compressed string will consist of one instance of each character in alphabetical order followed by the total count of that character within the string.

Run 
import java.util.*;

public class Main {
    public static String properCompression(String s) {
        StringBuilder compressedStr = new StringBuilder();

        for (int i = 0; i < s.length(); i += 2) { char c = s.charAt(i); int count = Character.getNumericValue(s.charAt(i + 1)); while (count > 0) {
                compressedStr.append(c);
                count--;
            }
        }

        return compressedStr.toString();
    }

    public static void main(String[] args) {
        String inputStr = "a3b5c2a2";
        String compressedResult = properCompression(inputStr);
        System.out.println(compressedResult);  // Output: "aaabbbbbcc"
    }
}

Q3. Write a  C++ Program to Change Decimal Number to Binary?

Run 
#include<iostream>
namespace std;
int main ()
{
  int a[10], n, i;
  cout << "Enter the number to convert: ";
  cin >> n;
  for (i = 0; n > 0; i++)
    {
      a[i] = n % 2;
      n = n / 2;
    }
  cout << "Binary of the given number= ";
  for (i = i - 1; i >= 0; i--)
    {
      cout << a[i];
    }
}

Q 4.C++ Program to generate Fibonacci Triangle

Run 
#include<iostream>  
using namespace std;  
int main()  
{  
    int a=0,b=1,i,c,n,j;    
    cout<<"Enter the limit: ";   
    cin>>n;    
    for(i=1; i<=n; i++)    
    {    
        a=0;    
        b=1;    
        cout<<b<<"\t";   
        for(j=1; j<i; j++)   
        {    
            c=a+b;    
          cout<<c<<"\t";    
            a=b;    
            b=c;  
        }    
        cout<<"\n";    
    }  
    return 0;  
}  

Q 5. What is the Output of the program

Run

include
Using namespace std;
int main()
{
  int a=5,b=10,c=15;
  int*arr[]={&a,&b,&c};
  cout<<arr[1];
  return 0;
}
  • 5
  • 10
  • 15
  • It will print their address of variable b.

Q 6. What is the Output of the program

Run

include 
Using namespace std;
int main()    
{
  Char arr[20];
  int i;
  for(i=0;i<10;i++)
  *(arr+i)=65 +1;
  *(arr+i)=0;
  cout<<arr; 
  return(o); 
}
  • ABCDEFGHIJ
  • AAAAAAAAAA
  • JJJJJJJJ
  • None of the above
Solution:-A

Q 7. What is the Output of the program

Run

 

#include<iostream> 
Using namespace std;
int main()
{
  char*ptr;
  Char Str[]="abcdefg";
  ptr=Str;
  ptr+=5;
  cout<<ptr;
  return 0;
}
  • fg
  • cdef
  • defg
  • abcd

Q8. For each element of an array of non-negative integers, arrin], is calculated as:
prefli] = arr[1JIJ⊕ arrl2JIJO . . . ⊕arrli]
Here x ⊕ y is the bitwise XOR of x and y. The array pref[n] contains the prefix XOR of all elements in arr[n]where 1 s is n.
1
2
Given the array pref, find the original array arr.
Note: There is always a unique arr for a given pref.

Run 
public class Main {
    public static int[] findOriginalArray(int[] pref) {
        int n = pref.length;
        int[] arr = new int[n];
        
        arr[0] = pref[0];
        for (int i = 1; i < n; i++) {
            arr[i] = pref[i] ^ pref[i - 1];
        }
        
        return arr;
    }

    public static void main(String[] args) {
        int[] pref = {3, 5, 2, 10};
        int[] originalArray = findOriginalArray(pref);
        
        System.out.print("Original Array: ");
        for (int num : originalArray) {
            System.out.print(num + " ");
        }
        // Output: Original Array: 3 8 10 2
    }
}
