Leetcode 1897. Redistribute Characters to Make All Strings Equal
You are given an array of strings?words
?(0-indexed).
In one operation, pick two?distinct?indices?i
?and?j
, where?words[i]
?is a non-empty string, and move?any?character from?words[i]
?to?any?position in?words[j]
.
Return?true
?if you can make?every?string in?words
?equal?using?any?number of operations,?and?false
?otherwise.
?
Example 1:
Input: words = ["abc","aabc","bc"]Output: trueExplanation: Move the first 'a' in words[1] to the front of words[2],
to make
words[1]
= "abc" and words[2] = "abc".
All the strings are now equal to "abc", so return true
.
Example 2:
Input: words = ["ab","a"]Output: falseExplanation: It is impossible to make all the strings equal using the operation.
?
Constraints:
1 <= words.length <= 100
1 <= words[i].length <= 100
words[i]
?consists of lowercase English letters.
