Given \(N\), how do I generate all the valid push/pop sequences (or draw all the trees)? I’ll generate the sequence of 1’s and 0’s....
We showed that the number of binary trees with \(N\) nodes is the Catalan numbers. It is also the number of valid push/pop sequences for...
Say we have the numbers from 1 to \(N\) in sequence. We will do a random sequence of pushes and pops into a stack: \(N\) pushes and...
A stack is a data structure for holding objects. It is a LIFO structure. It supports two operations: pop and push. pop returns (and...
