C++

Build and Run g++ code

g++ -std=c++17 -Wall -O2 -o "a" "a.cpp" && ./a < in
g++ -std=c++17 -Wall -O2 -o "program" "program.cpp"
export CPLUS_INCLUDE_PATH=/Library/Developer/CommandLineTools/usr/include/c++/v1/
g++ -std=c++17 -Wall -O2 -I/Library/Developer/CommandLineTools/usr/include/c++/v1/ -o "program" "program.cpp"

C++ Coding Convention

Rule 1: Check pointer is null or not, just use boolean operator (don't use null or nullptr)

/* Good way */
if(!node) { } 

/* Bad ways */
if(node != nullptr) { }
if(node != NULL){ }

VSCode Tips

Open multiple files

cd problems/leetcode_id

code -r cpp/main/solution.cpp cpp/main/solution.h data/1.in data/1.out data/2.in data/2.out data/3.in data/3.out

Run program

bazel run cpp/main:solution < data/1.in

Convert notebooks to README
