Question 1 - Past Year - 3 Mark Questions - Chapter 3 - Stacks

Write a function in Python PUSH(Arr), where Arr is a list of numbers. From this list push all numbers divisible by 5 into a stack implemented by using a list. Display the stack if it has at least one element, otherwise display appropriate error message.

Answer:

def PUSH(Arr):

stack=[]

for i in range(0,len(Arr)):

if Arr[i]%5==0:

stack.append(Arr[i])

if len(stack)==0:

print("Stack is Empty")

print(stack)
