60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    // Write your pointer logic here
    int a,b;
    if(*(mem) % 2 == 0 )
    {
        a = 0,b = 0;
    }
    else 
    {
        a = 0,b = 1;
    }
    for (int i = 0;i < k;i++)
    {
        if(*(mem + i) % 2 == a){
            if(i % 2 == b){}
            else {return 0;}
        }
        else if(*(mem + i) % 2 == b){
            if(i % 2 == a){}
            else {return 0;}
        }
    }
    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;
