60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int alt = 0;
    int i=0;
    int j=1;
    int *p0 = mem+i;
    int *p1 = mem+j;
    while (i,j<k)
    {
        if(*p0 == (*(mem+i)) && *p1 ==(*(mem+j)))
        {
            alt = 1;
        }
        else 
            alt = 0;
         
        i+=2;
        j+=2;
    }
    
    return alt;
}

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;
