My request is to make a compiler that transforms an expression like "add(5, mul(3, sub(10, pow(6, 4))))", in a equivalent mathematical expression, "5 + 3 * (10 - 6^4)" in this case.
Functions: add(x, y) (addition), sub(x, y) (subtraction), mul(x, y) (multiplication), div(x, y) (division), mod(x, y) (modulo), pow (x, y) (power), where x, y are operands
Operand: a number conforming to the following grammar:
<number> ::= <optional-sign> <digit-sequence> <optional-fraction> <optional-exponent>
<optional-sign> ::= "" | "+" | "-"
<optional-fraction> ::= "" | "." <digit-sequence>
<optional-exponent> ::= "" | "e" <optional-sign> <digit-sequence>
<digit-sequence> ::= <digit> | <digit> <digit-sequence>
<digit> ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Other elements: brackets ( and ) and whitespace (in the evaluated expression, there can be any number of whitespace characters, like spaces)
Desired result: A mathematical expression equivalent to the specified composition of functions. Make sure the order of operation application stays the same. Unnecessary brackets should be omitted.
The operator precedence has three levels, from lowest to highest:
1: +, -
2: *, /, %
The ^ operator is right associative, other operators are left associative.
Implementation language: C, C++ or Java
For lexical analysis, use regular expressions and finite automata; for syntax analysis, use context-free grammars and precedence-based parsing
ALL PARTS OF THE CODE MUST BE LARGELY COMMENTED!

Hello, sir. I have read your project details and thinking about the solution. I can do the project for u. I will finish it ASAP once you chose me. I will do it using C or C++. Thanks.
Hi, I have developed my own language called Drew with JVM. I am pretty sure I can get your task done. I can use either C or C++ as well. You want a transpiled langauge or a machine compile language?
