@ Shravan :- Thank for the Code but there are couple of issue with that..
1> Please try to provide the algo approach. Coz I feel
here we discuss irrespective of language , the technique of approach.
2> Your Code implementation of whatever your approach
is WRONG..
Please Run through these sample Inputs
Values :- 233556263
You need to make grow both the
stack Simultaneously.
Well Guys the Algo I presented above is my understanding as I feel its
simple topic being highly exaggerated. Please feel free to break it if I
have missed something..
