1016. Binary String With Substrings Representing 1 To N

Given a binary string s and a positive integer n, return true if the binary representation of all the integers in the range [1, n] are substrings of s, or false otherwise.

A substring is a contiguous sequence of characters within a string.

Example 1:

Input: s = "0110", n = 3
Output: true

Example 2:

Input: s = "0110", n = 4
Output: false

Constraints:

• 1 <= s.length <= 1000
• s[i] is either '0' or '1'.
• 1 <= n <= 109

impl Solution {
    pub fn query_string(s: String, n: i32) -> bool {
        for x in 1..=n {
            if !s.contains(&format!("{:b}", x)) {
                return false;
            }
        }

        true
    }
