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 cons_count = 0;
    int idx = 0;
    for(int i=1; i<n;i++){
        if(mem[i] - 1 == mem[i-1]){
            cons_count++;
        }else{
            cons_count = 0;
        }
        if(cons_count == 2)
            return i - 2;
    }
    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;
}
