There’s a french saying: “ qui peut le plus, peut le moins.”

If you can do difficult tasks, you’re capable of doing easier ones.

Leetcode exercises helped me make coding a data structure to solve a problem, second nature.

It gave me a problem solving confidence boost.

Day to day, it will help you much less, but it comes in handy when you hit that use case Leetcode trained you for.

Like realizing that a trie is valuable when doing a prefix name search in a Contacts application. You might have seen it in a CS class, but you won’t “believe” in it until you’ve implemented it yourself.
