Some Coding Questions for Practice

Question : 1

(asked in Wipro On Campus, Sastra University, Aug, 2019)

Problem: in this first line you are required to take the value of m and n as the number of rows and columns of matrix, then you are required to take the input elements of array.
As an output you are required to print the sum of each row then the row having the maximum sum.
Test Case :
Input : 3 3
1 2 3
4 5 6
7 8 9
Output :
Row 1 : 6
Row 2 : 15
Row 3 : 24
Row 3 is having the maximum sum : 24

C++

JAVA

Python

#include <stdio.h>

int main()
{
int row, colm, i, j, temp, max = 1;
int mat[100][100];
int sum[100];
printf("enter the number of rows : ");
scanf("%d",&row);
printf("enter the number of columms : ");
scanf("%d",&colm);
for(i=0; i<row; i++)
{
for(j=0; j<colm; j++)
{
printf("enter [%d %d] element : ",i+1,j+1);
scanf("%d",&mat[i][j]);
}
}

for(i=0; i<row; i++)
{
sum[i] = 0;
for(j=0; j<colm; j++)
{
sum[i] = sum[i] + mat[i][j];
}
printf("\n");
}

for(i=0; i<row; i++)
{
printf("Row %d : %d\n",i+1,sum[i]);
}

for(i=0; i<row; i++)
{
if(sum[0]<sum[i+1])
{
temp = sum[0];
sum [0] = sum[i+1];
sum[i+1] = temp;
max = max+1;
}
}

printf("\nRow %d is having the maximum sum : %d",max,sum[0]);

return 0;

Question : 4

(asked in Wipro On Campus, MIET Meerut, Aug, 2019)

Problem Statement

You are required to implement the following function:
Int SumNumberDivisible(int m, int n);

The function accepts 2 positive integer ‘m’ and ‘n’ as its arguments.
You are required to calculate the sum of numbers divisible both by 3 and 5, between ‘m’ and ‘n’ both inclusive and return the same.

Note
0 < m <= n

Example
Input:
m : 12
n : 50
Output 90

Explanation:
The numbers divisible by both 3 and 5, between 12 and 50 both inclusive are
{15, 30, 45} and their sum is 90.

Sample Input

m : 100
n : 160

Sample Output

405

C++

JAVA

Python

/* Programming Question */

#include <stdio.h>

int Calculate(int, int);

int main()
{
int m, n, result;

// Getting Input 

printf("Enter the value of m : ");
scanf("%d",&m);
printf("Enter the value of n : ");
scanf("%d",&n);

result = Calculate(n,m);

// Getting Output

printf("%d",result);

return 0;
}

/* Write your code below . . . */

int Calculate(int n, int m)
{
// Write your code here

int i, sum = 0;
for(i=m;i<=n;i++)
{
if((i%3==0)&&(i%5==0))
{
sum = sum + i;
}
}

return sum;

Question : 5

(asked in Wipro On Campus, Galgotia University Noida, Aug, 2019)

Input
The first line of input consists of three space separated integers. Num, start and end representing the size of list [N], the starting value of the range and the ending value of the range respectively.
The second line of input consists N space separated integers representing the distances of the employee from the company.

Output
Print space separated integers representing the ID’s of the employee whose distance liew within the given range else return -1.

Example
Input
6 30 50
29 38 12 48 39 55

Output
1 3 4

Explanation :
There are 3 employees with id 1, 3, 4 whose distance from the office lies within the given range.

{
scanf("%d",&a[i]);
}

for(i=0;i<num;i++)
{
if(a[i]>start && a[i]<end)
{
flag = 1;

    int r, odd=0, even=0, key;

    scanf("%d",&n);

    while(n!=0)
    {
        r = n%10;
        if(r%2==0)
        {
            even = even + r;
        }
        else
        {
            odd = odd + r;
        }
        n =  n/10;
