Great explanation. I’m about 10 problems away from solving 40 leetcodes which is my target to begin only doing mediums till I graduate.. this problem is super cool and this code is gonna help a lot. I keep forgetting that you can just use pop and that it returns the value and removes it. So, I’m glad your code made that easily readable and understandable. I love me some python for leetcode but damn Java’s collection library is really something else.. it’s making me want to make the switch

Time Complexity: O(n)
Space Complexity: O(n)
n: being the length of the array "tokens"

Thanks for sharing! I realized after I recorded that I forgot time and space complexity.

[@gothfrog69]

Thank you. Simple and clear!

[@dannynip]

Nice solution. I have a bad habit of not considering other data structures, so it's good to see other perspectives.

[@KeepOnCoding]

It just takes practice!

Nice channel)

[@casper8631]

that was great, I've got a question what happens when you are dividing is it possible to get a decimal number since your val2 is integer

[@TheGuroguro12]

Thanks

[@JimmieGirig]

Wow this was great. However, how should you do to be able to have multiple digit expressions?

I lost it at 4:13

@@KeepOnCoding Awesome thanks, really was annoyed by that white background! Nice! Also I've found if you launch Playground and select some theme theme lets say Monokai, then in any leetcode problem window, code style will be same.
