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

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

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

JimmieGirig

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
