C Exercises: Find the maximum repeating number in a given array
C Array: Exercise-81 with Solution
Write a program in C to find the maximum repeating number in a given array. The array range is [0..n-1] and the elements are in the range [0..k-1] and k<=n.
Sample Solution:
C Code:
#include <stdio.h>
int numToRepeatMax(int* arr1 , int n, int k)
{
int mx = arr1[0], result = 0;
for (int i = 0; i< n; i++)
arr1[arr1[i]%k] += k;
for (int i = 1; i < n; i++)
{
if (arr1[i] > mx)
{
mx = arr1[i];
result = i;
}
}
return result;
}
int main()
{
int arr1[] = {2, 3, 3, 5, 3, 4, 1, 7, 7, 7, 7};
int n = sizeof(arr1)/sizeof(arr1[0]);
int i;
//------------- print original array ------------------
printf("The given array is: \n");
for(i = 0; i < n; i++)
{
printf("%d ", arr1[i]);
}
printf("\n");
//------------------------------------------------------
int k = 8;
printf("The maximum repeating number is: %d", numToRepeatMax(arr1, n, k));
return 0;
}
Sample Output:
The given array is: 2 3 3 5 3 4 1 7 7 7 7 The maximum repeating number is: 7
