Traversal Through Strings.
Given a String S and a substring X , remove all occurences of X from S . Print the resulting String. If the resulting String has length = zero , print “0”(without quotes).
Python and Java users can simply use the replace() method which replaces all occurrences of a specified substring with another substring. If S and X are given , all that is needed to do is:
If Length is zero Print 0 else Print S .
This problem can also be solved by traversing through **S** and checking whether **X** is formed from ith to (i+l)th position where l=length of **X**.
Then We simply exclude the substring **X** if it is present at any part of **S**. ### AUTHOR'S SOLUTION: [Author's solution ](http://www.codechef.com/viewsolution/5576075).
