Code Signal_练习题_All Longest Strings

Posted 2020-12-24 yd2018

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

• [execution time limit] 4 seconds (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.

 

 

我的解答：

1 def allLongestStrings(inputArray):
2     li = []
3     m = max(inputArray,key=len)
4     for i in inputArray:
5         if len(i) == len(m):
6             li.append(i)
7     return li

 

膜拜大佬：

1 def allLongestStrings(inputArray):
2     m = max(len(s) for s in inputArray)
3     r = [s for s in inputArray if len(s) == m]
4     return r

虽然代码比大佬写的多，但至少想法一样了....
