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; i++){

        int a = *(mem+i);
        int b = *(mem+i+1);
        int c = *(mem+i+2);

        if ((b == (a+1)) && (c == (b+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;
}
