Suppose you have a stack in when the values 1 through 5 must be pushed on the stack in that order, but that an item o the stack can be popped and printed at at time. So for example, the operations

s.push(1)

s.push(2)

print s.pop()

s.push(3)

s.push(4)

print s.pop()

s..push(5)

print s.pop()

print s.pop()

print s.pop()

produce the sequence 2 4 5 3 1. Based on the constrains mentioned above , give the list of operations that would produce each of the following sequences. if is not possible. state so a. 1 3 5 4 2 b. 2 3 4 5 1
