ONP - Transform the Expression
Transform the algebraic expression with brackets into RPN form (Reverse Polish Notation). Two-argument operators: +, -, *, /, ^ (priority from the lowest to the highest), brackets ( ). Operands: only letters: a,b,...,z. Assume that there is only one RPN form (no expressions like a*b*c).
t [the number of expressions <= 100] expression [length <= 400] [other expressions]
Text grouped in [ ] does not appear in the input file.
The expressions in RPN form, one per line.
Input: 3 (a+(b*c)) ((a+b)*(z+x)) ((a+t)*((b+(a+c))^(c+d))) Output: abc*+ ab+zx+* at+bac++cd+^*
solved this with recursion
lol I did rly stupid i didn't use stack i created dumb token class and separate on operator but it works anyways i think maybe logn times slower than stack
Why I keep geting runtime error (NZEC) ?
Just use stack
got me stuck for an hour because I took expression length to be 100.. : (

Why would my code take 16M Memory to execute?
solved by using just stack in one go...!
There is a problem in test cases. My solution is AC in first attempt but later I found out it gives wrong output in those testcases which are without brackets. For example: "a*b+c"
