Remove Substrings in One Iteration in python

Suppose we have a string s, we have to remove all “y” and “xz” in the string in one iteration.

So, if the input is like s = "xyxxzyyxxzx", then the output will be xxxx

To solve this, we will follow these steps −

To solve this, we will follow these steps −

• temp := string after removing xz
• return temp after removing y

Let us see the following implementation to get better understanding −

Example

 Live Demo

class Solution:
   def solve(self, s):
      return s.replace("xz","").replace("y","")
ob = Solution()
print(ob.solve("xyxxzyyxxzx"))

Input

"xyxxzyyxxzx"

Output

xxxx
