Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k, int n) {
    // Write your pointer logic here
   int *p = mem;
   int *p1 = mem+1;
    for(int i=0; i<k-1; i++)
    {
       if(*p == *p1)
       return 0;

       p++;
       p1++;
    }
    return 1;
}

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, n);
    printf("%d", res);

    return 0;
}
