Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    int status=2;
    for(int i=0;i<k-2;i++)
    {
        if(*(mem+i)==*(mem+i+2))
        {
            status=1;
        }
        else
        {
            return 0;
        }
    }
    return status;
}

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;
}
