Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int* address = mem;
 
    for(int i=0; i<n; i++) {
        if(((*mem + 1) == *(mem+1)) && ((*mem + 2) == *(mem+2))) {
           return mem - address;
        }
        mem++;
    }
    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;
}
