Following is C like Pseudo code of a function that takes a number as an argument, and uses a stack S to do processing. void fun(int n) { Stack S;//Say it creates an empty stack S while(n>0) { // This line pushes the value of ... . Prints binary representation of $n$. Prints the value of $\log n$. Prints the value of $\log n$ in reverse order.
