Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int op =0;
    int i=1;
    int *ptr = mem;
    while(i<k){
        if((*(ptr) ^ *(ptr+1))==0) break;
        ptr++;
        i++;
    }
    if (i==k) op=1;
    return op;
}

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;
}
