Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    int streak = 1;
    for (int i = 0; i < k-1; i++){
        int current = *(mem +i );
        int next = *(mem +i + 1);
        if (current ^ next){
            streak ++;
        }
    }
    if (streak == k){
            return 1;
        }else {
            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;
}
