Sort Integers by The Number of 1 Bits
In this lab, you will be given an integer array
arr and your task is to sort the integers in the array in ascending order based on the number of
1's in their binary representation. In case two or more integers have the same number of
1's, you have to sort them in ascending order.
To achieve this, you need to implement the function
sortByBits(arr) that takes an array of integers as input and returns a new sorted array based on the mentioned conditions.
Input: arr = [0,1,2,3,4,5,6,7,8] Output: [0,1,2,4,8,3,5,6,7] Explanation:  is the only integer with 0 bits. [1,2,4,8] all have 1 bit. [3,5,6] have 2 bits.  has 3 bits. The sorted array by bits is [0,1,2,4,8,3,5,6,7]
Input: arr = [1024,512,256,128,64,32,16,8,4,2,1] Output: [1,2,4,8,16,32,64,128,256,512,1024] Explanation: All integers have 1 bit in the binary representation, you should just sort them in ascending order.
1 <= arr.length <= 500
0 <= arr[i] <= 10^4
Now, after understanding the problem statement and conditions, you need to work on the following challenges:
- Export the
- Implement the
