The main challenge of this question is the … WebJava solution to Codility PermMissingElem (Permutation Missing Element) problem (Lesson 3 – Time Complexity) which scored 100%. The problem is to find the missing element in a given permutation. The main strategy is use a HashSet to store elements which will also order them. Then check all values from 1 to max to see if it’s missing from HashSet.

Next we calculate the 'ordinary' series sum, assuming the first element in the series is always 1. Then we find the difference between the given array and the full series, and return it. This is the missing element. new harlem cologne
