Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k)
{
    // Write your pointer logic here
    int temp = *mem;
    ++mem;
    int m = 1;
    while (*mem != temp)
    {
        m = m + 1;
        if (m == k)
        {
            if (*mem != temp)
            {
                return 1;
            }
        }
        temp = *mem;
        ++mem;
    }
    return 0;
}

int main()
{
    int n, k, arr[100];
    scanf("%d %d", &n, &k);

    for (int i = 0; i < n; i++)
    {
        scanf("%d", &arr[i]);
    }

    int res = is_alternating_pattern(arr, k);
    printf("%d", res);

    return 0;
}
