Given an array of distinct integers, this problem asks you to find the length of the longest subsequence in which the elements are strictly increasing. For example, given the array [1,3 ,2,4], the longest increasing subsequence would be [1,2,4], so the answer would be 3.

Given a string, this algorithm finds the length of the longest substring within that string that does not contain any repeating characters. For example, given the input string "abcabcbb", the algorithm would output 3, since the longest substring without any repeating characters within that string is "abc".

Given an array of strings, this problem looks for the longest common prefix. This is the string that is shared by all of the strings in the array, and is typically the shortest string in the array.
