Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int i = 0;
    while(i < k - 1){
        int current = *(mem + i);
        int next    = *(mem + i + 1);
        int case1 = (current == 1 && next == 0);
        int case2 = (current == 0 && next == 1);
        if(case1 || case2){
            i++;
        }else{
            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;
}
