Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    if(n < 3)
        return -1;
    for(int i = 0; i < n - 2; i++){
        int current = *(mem + i);
        int next1 = *(mem + i + 1);
        int next2 = *(mem + i + 2);
        if((next1 == current + 1) &&(next2 == current + 2))
            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;
}
