I am new to Leetcode and have been practicing on the Easy level algorithms. Some of those 'easy' questions takes me a minute to solve, but there are some that I feel is not easy at all. It will take me more than 30 minutes to solve them.

Couple questions.

1. Do others also feel some of the 'easy' questions aren't that easy?
2. What is a good target on the amount of time to solve these questions?
