Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    int index = -1;
    int cnt = 0;
    for(int i = 0; i < n - 1; i++){
        if(*(mem + i + 1) - *(mem + i) == 1){
            if(cnt == 0) index = i;
            cnt++;
            if(cnt == 2) break;
        } else {
            cnt = 0; 
            index = -1;
        }
    }
    return index;
}

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;
}
