Understanding the Number of Steps to Reduce a Number in Binary Representation to One Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given the binary representation of an integer as a string s, return the number of steps to reduce it to 1 under the following rules: If the current number is even, you have to divide it by 2. If the current number is odd, you have to add 1 to it. It is guaranteed that you can always reach one for all test cases.

Examples
s = "1101"6"1101" corressponds to number 13 in their decimal representation. Step 1) 13 is odd, add 1 and obtain 14. Step 2) 14 is even, divide by 2 and obtain 7. Step 3) 7 is odd, add 1 and obtain 8. Step 4) 8 is even, divide by 2 and obtain 4. Step 5) 4 is even, divide by 2 and obtain 2. Step 6) 2 is even, divide by 2 and obtain 1.
s = "10"1"10" corresponds to number 2 in their decimal representation. Step 1) 2 is even, divide by 2 and obtain 1.
s = "1"0Constraints
1 <= s.length <= 500s consists of characters '0' or '1's[0] == '1'How Interview Coder Helps with Leetcode Problems
