1016. Binary String With Substrings Representing 1 To N ¶

Problem

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
