brother now are you doing now? after 3 years?

[@coolgoose8555]

I have been watching your videos from sometime now... I have been working from long time in the industry and it's been to get a quick refresher of these concepts which are fundamental to CS. Not only these videos are relevant to students in school but equally relevant to folks who are working in industry or even preparing for interviews..... This is very good work.... I think it would also be great if you add section in your videos where you can also go through applications of the the algorithm..... Prof. Sedgwick videos are pretty good on that format but it very limited and only about certain topics..... Something to consider as I see you have large community and its only going to grow.... Good work!!!!

If the precedence of the incoming operator is higher than the operator at the top of the stack then directly push the incoming operator in the stack. If it's lower,pop the operator at the top of the stack and then compare the incoming operator with the operator at the top of stack. If the precedence is same then check associativity.If associativity left to right then pop the top of the stack.If it is right to left then add the incoming operator to stack.

[@sworupmudbhari]

Instead of using array, we can also use linked list to implement stack. Linked list allocates the memory dynamically. However, time complexity in both the scenario is same for all the operations i.e. push, pop and peek. In linked list implementation of stack, the nodes are maintained non-contiguously in the memory. Each node contains a pointer to its immediate successor node in the stack. Stack is said to be overflown if the space left in the memory heap is not enough to create a node.

[@manaschoudhary2079]

Mam, In the rules you have told that if equal precedence operator has come then simply pop out top of the stack and print and after that simple push the incoming operator.But in example you have recheck the the incoming operator with stack even after poping.How??? I'm little bit confused.
