Detect Alternating Pattern

Code

#include <stdio.h>
#include <stdbool.h>

int is_alternating_pattern(int *mem, int k) {
    
    bool isPatternDetected = false;

    bool next_value=0, current_value =0;
    for(int i=0; i<k-1 ;i++)
    {

        current_value = *mem;
        next_value = *(mem+1);

        if(current_value==next_value)
        {
            return 0;
        }

        
        mem++;
    }

    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;
}
