// 0-63 represented in 6 bits. therefore there are 6 parities
/*
- Use getline(cin, [string var]); to grab the ENTIRE string because it is safer
- "typedef" to shorten data types, ex long long -> ll
- #define to change commands
- __LINE__ shows the line of code it's currently running
- #v shows the name of the variable itself
- vector<data_type> variable_name(n, x) creates a vector of size n, all containing value x
- stable_partition(l, r, f) means that from iterator l to r, a function f will be executed. {a<ll>, b<ll>}.
* If f's value if true, the value of iterator relocated to a. else go to b. replaces the value of iterator from l to r.
- LLONG_MAX is max of long long
RUNNING INTERACTIVE PROBLEMS:
- In terminal: "cd [folder_name]" to transverse
- g++ [headerfiles] [funct files] [grader file]
- ./[exec file created]
