3908. Valid Digit Number

You are given an integer n and a digit x.

A number is considered valid if:

• It contains at least one occurrence of digit x, and
• It does not start with digit x.

Return true if n is valid, otherwise return false.

class Solution {
public:
    bool validDigit(int n, int x) {
        bool has = false;
        while(n >= 10) {
            has |= n % 10 == x;
            n /= 10;
        }
        return has and n != x;
    }
