Code Fights - allLongestStrings

README.md

Given an array of strings, return another array containing all of its longest strings.

Example

For inputArray = ["aba", "aa", "ad", "vcd", "aba"], the output should be
allLongestStrings(inputArray) = ["aba", "vcd", "aba"].

Input/Output

• [time limit] 4000ms (py3)

• [input] array.string inputArray

  • A non-empty array.

Guaranteed constraints:

1 ≤ inputArray.length ≤ 10,
1 ≤ inputArray[i].length ≤ 10.

• [output] array.string

  • Array of the longest strings, stored in the same order as in the inputArray.
