Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int temp = 0;
    for(int i = 0; i < n; i++){
        if((*(mem + i + 1) - *(mem + i) == 1)){
            temp++;
        }
        else{
            temp = 0;
        }

        if(temp == 2){
            return (i-1);
        }
    }

    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;
}
