Earlier, we were directly storing the elements in the stack, but now we will store an integer value from 0 or 1. A value of 0 will denote that we are inserting characters in the stack, and 1 will denote that we have removed the characters by pressing the backspace button. This differentiation of the operations will help us in implementing the undo functionality properly, because ...
