Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    int _temp = 1;
    for(int i = 0; i< k - 1; i++)
    {
        if(*(mem+i) ^ *(mem + i + 1))
        {
            _temp ++;
        }
        if(_temp == k)
        {
            return 1;
        }
    }
    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;
}
