Alam has a list containing 10 integers. You need to help him create a program with separate user defined functions to perform the following operations based on this list.
- Traverse the content of the list and push the even numbers into a stack.
- Pop and display the content of the stack.
For Example: If the sample Content of the list is as follows: N=[12, 13, 34, 56, 21, 79, 98, 22, 35, 38]
Sample Output of the code should be: 38 22 98 56 34 12
Answer
Program:
list1 = [
12
,
13
,
34
,
56
,
21
,
79
,
98
,
22
,
35
,
38
]
def
func_push
(stack, num):
stack.append(num)
#it appends the received value to the stack
def
func_pop
(stack):
if stack != []:
return stack.pop()
#return the topmost value if stack is not empty
else:
return None
myStack = []
for i in list1:
#i represents each value of list1 at a time
if i%
2
==
0
:
#check for even numbers
func_push(myStack, i)
#if value is even, it is pushed in stack
while True:
if myStack != []:
#check if the stack is empty or not
print(func_pop(myStack), end =
" "
)
#if not empty, then pop out values
else:
break
Output:
38 22 98 56 34 12
