Same here! I'm used to Python and just finished a Java crash course. Went straight here so I could learn all the different methods I could use.

omg

What is regex? I probably sound like a noob...

Genius! I took like so much longer to get this right, using if statements and stuff.

EYYYYYYYYYYY!

not readable, not reccomended

Nice ,short, and clean code congratulation !!

perfect examples of a simple problem solved with something that is really not worth trying to understand

This solution uses two loops (filter and sum) instead of one for loop in the traditional one. So yes, in the terms of performance this is definitely not the best solution.

Nice solution but mine better haha :)

yes. There are so intelligent people.

nice move dude

Can someone please explain why this solution is most voted as Best Practices? it's a concise one-liner but I thought loop-based solution might be more appropriate.
