Sort Characters By Frequency | Leetcode
This video explains a very important programming interview question which is to rearrange the string in such a way that all the highest frequency characters occurs first followed by 2nd highest frequency characters and so on till the least frequent character. The new string must contain the same number of each unique character and the relative order of two unique characters with same frequency is not important. Therefore, we can have multiple answers to the same input string. I have shown the solution using a simple hash method using array of pairs. At the end of the video, i have explained the CODE and CODE LINK is present below as usual. If you find any difficulty or have any query then do COMMENT below.
