Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int res = 1;
    for(int i = 0; i< k-1; i++){
        int *p1 = mem +i;
        int *p2 = mem +i +1;
        if(*p1 == *p2){
            res =  0;
            break;
        }
    }
    return res;
}

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;
}
