Hi, can you please explain how this solution works? I am trying to prepare for a coding contest. Thank you so much!

No understanding the Uonorderd map part

Hi, Thanks for putting up the solution. I am trying to solve this using javascript but my code fails for 7 test cases out of 27. Kattis does not give the test cases for which it is failing. can you please explain the below part:

unordered_map<int,int> seen;
for(int i = 0; i < n; i++) {
int temp;
cin >> temp;
seen[temp]++;
}

Won't compile with clang: <bits/stdc++.h> not found

When compiling it, I got

$ clang++ -o smallschedule{,.cpp}
smallschedule.cpp:1:10: fatal error: 'bits/stdc++.h' file not found
#include <bits/stdc++.h>
         ^~~~~~~~~~~~~~~
1 error generated.

Apparently that's a gcc-only header that my clang doesn't understand, replacing that line with

#include <iostream>

Fixes it.

It's kinda annoying that kattis doesn't show the input for which a solution fails, so I just hacked something together that uses random data as input and compares my solution to yours to find cases where mine is wrong. Thanks for putting this up!
