60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int *ptr = mem;
    int flag = 0;
    for (int i = 0; i < k - 1; i++){
        if (*ptr ^ *(ptr + 1) == 1)
            flag = 1;
        else
            return 0;
        ptr++;
    }
    return flag;
}

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;
}
