Study Notes
Solving a Binary Question: Counting Bits
- The problem is to count the number of ones in the binary representation of each number in a given range.
- This problem is part of the Blind 75 list, a collection of binary questions.
- The problem was initially rated as medium difficulty but was later changed to easy.
- The input is an integer, n, and the output should be an array of length n+1.
- The array represents the count of ones in the binary representation of each number in the range from 0 to n.
- For example, if n is 0, the output array will have a single integer representing the count of ones in the binary representation of 0.
- If n is 2, the output array will have three integers representing the count of ones in the binary representation of 0, 1, and 2.
- The task is to find the count of ones for each number in the range 0 to n.
- The problem statement is simple and straightforward.
- The solution will be provided in a video format.
- The goal is to add a video solution to this binary problem.
- The problem is part of a spreadsheet that tracks solutions for the Blind 75 list.
