ps.cpp

General-purpose header-only modern c++(20+) library with well-abstracted algorithm and data structure implementations. It's useful for solving algorithmic problems, but not limited to it.

Interface

1. [s,e) half opened range
2. 0-based-index
3. Support negative index (same as python) (only suppoerted in Arr<T> as of now)

Getting Started

Requirements: ubuntu(20.04+), g++(10.3.0+)

  git clone https://github.com/tuxedcat/ps.cpp
  cd ps.cpp
  tool/build_cmake.sh src/sample/helloworld.cpp Debug
  cat build/submit.cpp #It resolves all header file dependancies and merge them into build/sumit.cpp
  build/src/sample/helloworld.cpp/Debug/ps.cpp.out

Sample Code

#include "core/base.h"
i32 main(){
	//Can get arbitrary tuple from stdin
	auto [n,m,k,x]=input<int,short,int,string>();
	//Can create and read dynamic array of arbitrary dimension
	//This creates n*m*k dynamic array, then read values from stdin
	auto a=input(ARR(n,m,k,0ll));
	//Can print an arbitrary tuple and dynamic array
	dbg(n,m,make_tuple(k,x),a);
}

Sample Input

2 3 2 hi
1 2
3 4
5 6
0 0
1 1
2 2

Sample Output

n,m,make_tuple(k,x),a;=
<  2,  3,
-<  2, hi,>,
-{
--(
---[  1,  2,],
---[  3,  4,],
---[  5,  6,],),
--(
---[  0,  0,],
---[  1,  1,],
---[  2,  2,],),},>

Optional Settings: Testcase Download

1. Install CompetitiveCompanion extension to your webbrowser
2. Install nodev14+ and expressjs
3. Run node tool/tcsaver.js
4. Click the extension on webbrowser will download all examples on current page into ./test/*
5. Run tool/tc.sh [executable file path] will check all output automatically.

VSCode

You can use preset VSCode tasks. For more information, .vscode/tasks.json

Limitation

1. Due to dependancy resolving logic, #include must be located on top of source file.
2. Don't use Subtyping-Polymorphism. (pslib assume this for simple code)
