中文文档

Description

Given a binary string S (a string consisting only of '0' and '1's) and a positive integer N, return true if and only if for every integer X from 1 to N, the binary representation of X is a substring of S.

 

Example 1:

Input: S = "0110", N = 3

Output: true

Example 2:

Input: S = "0110", N = 4

Output: false

 

Note:

1. 1 <= S.length <= 1000
2. 1 <= N <= 10^9
