Detect Alternating Pattern

Code

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
   
   int i=0;
   int *curr=mem;
   while(i < k-1){
        if(*curr == 0){
            if(*(curr+1)!=1)
                return 0;
        }
        
        if(*curr == 1){
            if(*(curr+1)!=0)
                return 0;
        }
        i++;
        curr++;
   }
    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;
}
