Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    for(int i=0;i<k;i++){
        if((*(mem+i)==*(mem+2+i))&&(*(mem+1+i)!=*(mem+i))){
            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;
}
