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 a=0;
    for(int i=0;i<=(n-3);i++){
        if (((*(mem+i)+1)==*(mem + (i+1)) && (*(mem+(i+1)+1)==*(mem+(i+2))))) {
            return i;
            a=1;
            break;
        }
    }
    if (a==0) 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;
}
