Generate random arithmetic expressions, that have N literals, each literal is integer and does not exceed M in absolute value. Expression evaluation result should not exceed M in absolute value as well.

Allowed arithmetic operations: addition, subtraction, multiplication, division. Operations have usual precedence and left associativity.

• Implementation should read N and M from file and/or command line arguments.
• Expression should not contain redundant parentheses. For instance, ((5+(6*7)) should actually be 5+6*7, whereas 5*(-2) has no redundant parentheses.
• Generation should be comprehensive.

1. Install stack + ghc or libtinfo5

2. Run stack install in project root to compile and copy binary file to stack local bin storage (by default: ~/.local/bin)

   Useful commands:

   • stack build - compile only
   • stack ghci - run REPL with project modules
   • stack test - run unit tests

3. Run exprgen --help for further instructions

   Example: exprgen -n 10 -m 20 -s 1
