Answer #1

Solution

Push-inserting elements into the stack

Pop-deleting elements from the stack

Stack follows LIFO policy

LIFO-Last In First Out

Last Inserted element will be out first

push(a)

“a” is pushed into stack

a

push(b)

“b” is pushed into stack

b

a

pop

top of the item will be popped out so “b” will be popped out

a

push(c)

“c” will be pushed into stack

c

a

push(d)

“d” will be pushed into stack

d

c

a

pop

top of the element “d” will be popped out

c

a

final stack

c

a

Suppose that a client performs an intermixed sequence of Stack push and pop operations. The push operations put the integers 0 through 9 in order onto the Stack. That is, the following operations must appear in this order with any number of pop operations in between: push(0), push(1), …, push(8), push(9). Each pop operation pops the top item off the Stack and prints the return value. Determine if each of the following sequences can or cannot be a result of...

Use the following algorithm: (1) Create three stacks of characters: stk1, stk2, stk3. (2) Read the input infix expression one character at a time and push every character read ( other than ')' ) onto stk1. Do not push the character read if it is ')'. (3) As long as stk1 is not empty, do the following:            Fetch the top character ( call it c ) of stk1 and pop stk1.            if c is an alphabetic character (a-z),...
