    1:28:48 logic
    jo phle number hoga wo infix ka left side se chalu hoga (v1) agar niche wale ko v2 ki jgh v1 bana denge to ordering kharab ho jayegi
    or jo evaluate kar rhe hai wo glt ho jayega
    prefix mai loop ulta isliye chal rha kyo ki prefix mai jo operators hote hai wo hamesha left side me hote hai OP_V1V2
    agar ulta loop chalyenge to number phle dal payenge or evauluation ho jayegi agar agey se karenge to operators a jaeyga par unke corresponding numbers ni milenge or glt evaluate ho jayega
    but piche se karenge to to shi hoga jaise hi number ke bad operator ayega wo usi number ke corresponding hoga to evaluation mai gadbad nhi hogi
    hope this clear the doubts !!!

    I think the code is wrong or it need more adjustment of prefix as we have to first the operand like * or /
    Directly just solve question 3+6+8*4+7 and dry run it you understand what i want to tell?
    The ans must be +++36*847 but ans coming is ++36+*847

      @Ankitpanwar-z7c 3 месяца назад

      indeed!
      this approach will not work in some cases where negative sign followed is "*" or "/".
      eg:- 5+2-2*2+2.
      eg:- 1*2-3/4+5*6-7*8+9/10 (this one is test case form leetcode question 227 basic calculator.)
