Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

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