What is the output of input "192761"?

Answer 1

for first while loop:

we push the character onto the stack we have till we have characters in the word  : 192761 into the stack.

for second while loop :

 pop is called and than printed,

as : 167291

@shaik masthan : yes bro but popped values will be printed in reverse.

Why popped values print in reverse... After popping., you immediately print...

I hope, you mistakenly assume that, printing the elements statement is not under while loop.... Check one more time

@shaikh u are right i assumed pop as a function call . my mistake i accept. updated thanks:p
