Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    for(int i  = 0 ;i <n -2; i++){
        int *tmp1 = mem + i;
        int *tmp2 = mem + i + 1;
        int *tmp3 = mem + i + 2;
        if((*tmp2 - *tmp1) == 1 && (*tmp3 - *tmp2) == 1){
            return i;
        }
    }
    return -1;
}

int main() {
    int n, arr[100];
    scanf("%d", &n);

    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int res = find_pattern(arr, n);
    printf("%d", res);

    return 0;
}
