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 cnt = 0; int index = 0; int flag = -1;
    for(int i = 0 ; i < n ; i++){
        if(*(mem + i + 1) - *(mem + i) == 1){
            //flag = i + 1;
            index++;
            if(index == 2 && *(mem + i + 1) - *(mem + i) == 1){
                flag = i + 1 ;
				return flag - 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;
}
