60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Crawl backwards over the mem & compare if 2 adjacent values are the same
    while (k-- && k > 0){
        int *cur_val = mem+k;
        int *prev_val = mem+k-1;
        //printf("Current val: %d, Prev val: %d, k: %d\n", *cur_val, *prev_val,k);
        if(*cur_val == *prev_val){
            return 0;
        } 
    }
    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);
    printf("%d", res);

    return 0;
}
