Method #2 : Using len() + key argument + min(). Can I trust my bikes frame after I was hit by a car if there's no visible cracking? I have a high level general question, do you think building trie tree improve the algorithm performance? Most people will give up and instead come up with their own implementations. Use the for loopto traverse the words in the list and keep track of the shortest word as you are iterating. Time Complexity: O(n)Auxiliary Space: O(n), where n is the length of the list. Just like find the minimal or max value of an array, but you have to use a list to store all the "min"s instead of a variable. We then used a conditional statement to return the index number (i) when the value (j) is equal to the min(length) for shortest string, and max(length) for longest string. This tutorial will show you how to get the index of the shortest and longest strings in list in the Python programming language. Below are my comments: This has runtime \$(n^2)\$, same as the code in the post, but it's a lot shorter. Don't have much experience with trie. rev2023.6.2.43474. Lets take a look!
