}
}

Output =>
Stack elements are as follows :
10
20
30
40
50
60
70
80
90
popping as LIFO is 90 and now stack elements are as follows:
10
20
30
40
50
60
70
80
popping as LIFO is 80 and now stack elements are as follows:
10
20
30
40
50
60
70
popping as LIFO is 70 and now stack elements are as follows:
10
20
30
40
50
60
popping as LIFO is 60 and now stack elements are as follows:
10
20
30
40
50
Stack capacity: 10
Stack size: 5
Popping the elements: 50
Popping the elements: 40
Popping the elements: 30
Popping the elements: 20
Popping the elements: 10


Now the stack size is 0
Now the stack capacity is 10
