Run by online IDE

• Navigate to \ParenthesesFormatter\ForOnlineIDE
• Simply copy whole chunk of code
• Paste it to https://nextleap.app/online-compiler/go-programming
• Fill our input and run
• You can find sample input in the input.txt file

Run by go command

• Install go first https://go.dev/doc/install
• Navigate to /ParenthesesFormatter
• go run .

Run by executable file

• Please build the executable file first if you want to use this method
• For windows environment, use powershell or command line .\ParenthesesFormatter.exe to run.
• For Mac you should able to run by ./hello once executable is built
• ParenthesesFormatter will take stdin as input and output to stdout (need to ctrl+c to stop then you can see stdout)
• Support mutiple line input
• For example,

input file:

(A*(B+C))
1*(2+(3*(4+5)))
2+(3/-5)

output file:

A*(B+C)
1*(2+3*(4+5))
2+3/-5

• Also if you're using powershell. There will also console messages for human.

console output:

(A*(B+C)) => A*(B+C)
1*(2+(3*(4+5))) => 1*(2+3*(4+5))
2+(3/-5) => 2+3/-5

Build executable file

• We need to install go first https://go.dev/doc/install
• Change to directory \ParenthesesFormatter
• run go build ./... to build whole project. This will create/renew our ParenthesesFormatter.exe or other executables.

Run tests via VScode

• After we've installed GO and VScode
• Install extension Go for Visual Studio Code
• In the file formatter_test.go, we should just able to use VScode's integrated testing function

Some constraints about the function

• In this function, I am assuming all of the input would contains valid parentheses pairs.
• That is we will see something like (()) but not (().
• Since if we want to auto correct invalid pairs like (a*(b+c).
• The result could be a*(b+c) or (a*b+c), causing our ParenthesesFormatter will have different output.
