All Longest Strings

Description


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] 500ms (cpp)
  • [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.
