    BRUH this video actually saved me for my coding assignment (use a stack to convert an infix string to prefix). ALL the coding websites claim that all you have to do is reverse the string, then do the usual infix to postfix conversion, then reverse the resulting string. What they DON'T tell you is that you do NOT pop operators of the SAME priority. All it took was a quick skim through your video to figure out what had gone wrong. Thanks Jenny!

    you have explained each and everything in a perfect way, earlier I was having a lot's of doubt in "infix in prefix" but you cleared.
    You are the excellent teacher of Data Structure.
    Thank you so much to make a video on this topic.

    First of all a great great thanks to dear Jenny Teacher.
    I salute her for teaching such a tough topic of DSA in very simple and easy manner.
    When I was in class 6th I use to think how to solve a math expression in Java and C .
    Then when I learnt the INFIX prefix and postfix then I coded my own mathematical Calculation Program in C++.
    Thanks once again mam for your great help by teaching.
    I salute you mam

    Ma'am, in your previous lectures you had taught that if both the incoming and the 'top-of-the-stack' operators have the same precedence and thereafter associativity of 'Left-right', then we need to pop the top of the stack before storing the incoming operator. But here in the 8th step, you pushed the incoming operator instead.

    • @dominicpeng8802
      @dominicpeng8802 4 роки тому +10

      that should be the infix to postfix case because in the prefix case you are scanning the string reversely which leads to reversed associativities rules

    • @gracenote108
      @gracenote108 4 роки тому +4

      @@dominicpeng8802 So I'm actually wondering the samething. Other guides say that we should follow the postfix style operator associativity rules since we already reversed the expression.

    • @ZahidHasan-sv2sh
      @ZahidHasan-sv2sh 4 роки тому

    • @matthewadams4097
      @matthewadams4097 3 роки тому +5

      Guys, basically if you're just doing infix->postfix you just loop the condition
      while (precedence(operator) top)
      pop
      finally push
      if doing infix->prefix, reverse the string and then do the same process as postfixing but instead the condition for operators is
      while (precedence(operator) < precedence(operator at stack->top)
      pop
      finally push
      (At the end reverse again)
      Hope this helped
