Getting WA when using same code but replace Set with Map
By rakkoon69, history, 21 month(s) ago, In English

Can someone please explain to me why this 195043061 gives WA on test 7 while 195042850 got AC. The only difference is the first submission used Map while the second one used Set. Thanks in advance!

Your code checks map and inserts new values when it's not found. This code uses map.count and passes.
