(HackerRank) Write a Modular C Programming code to solve Maximum sum 16, Given a matrix of order R * C, display all the column numbers that have the maximum sum
Given a matrix of order R * C, display all the column numbers that have a maximum sum
Input Format
The first line contains two integers R and C, the order of the matrix separated by a space.
The next line contains R * C integers separated by a space
Constraints
1<= R,C<=100
Output Format
In one display all the column numbers in each line that have maximum sum
Note: Column number starts from zero.
Sample Input 0
0 5
Sample Output 0
Invalid
Sample Input 1
3 3
2 2 3 9 5 6 7 8 9
Sample Output 1
0
2
Explanation 1
Sum of 0th Col = 18
Sum of 1st Col = 15
Sum of 2nd Col = 18
CODE:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
int main() {
int r,c;
scanf("%d%d",&r,&c);
if(r>1 && c>1)
{
int num[r][c],i,j,colsum[c];
for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
{
scanf("%d",&num[i][j]);
}
}
for(i=0;i<c;i++)
{
colsum[i]=0;
for(j=0;j<r;j++)
{
colsum[i]+=num[j][i];
}
}
int max=colsum[0];
for(i=0;i<c;i++)
{
if(max<colsum[i])
max=colsum[i];
}
for(i=0;i<c;i++)
{
if(max==colsum[i])
printf("%d\n",i);
}
}
else{
printf("Invalid");
}
return 0;
}
}
