WebJul 21, 2024 · 1.1 – The Approach Iterating over every element in a list leads to linear time complexity. In a HashMap, we avoid this traversal by calculating the position of an element based on its key. Let’s assume we have only 26 places in our list. We assign the lowercase alphabets as the keys. So a points to position 1, b points to 2 and so on.
