60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int *ptr = mem;
    int *ptr1 = mem + 1;
    int count = 0;
    for(int i=0; i<k-1; i++){
        if(*ptr != *ptr1){
            count++;
            if(count == k-1 ) return 1;
        }
        ptr++;
        ptr1++;
    }
    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;
}
