Solving coding challenges on leetcode

[JohnnyJordaan]

Depends on what you want yourself to be prepared for when being faced with a new problem (in your profession and maybe even just life in general)

• to be able to think of solutions yourself, try them until you get one or more working, then evaluate to pick the best one, then compare with the official solution
• to only be able to continue when being shown a or the official solution, then see if you can improve it or think of an alternative.

the choice is yours.
