I found an interesting problem on https://leetcode.com/problems/find-the-difference/:
Given two strings s and t which consist of only lowercase letters.

String t is generated by random shuffling string s and then add one more letter at a random position.

Find the letter that was added in t.

Example:

Input:
s = "abcd"
t = "abcde"

Output:
e

Explanation:
'e' is the letter that was added.

I tried it in Python, but could not do it. Can you solve it?

 What is a Python program to find the letter that was added in t?

#Here is Python program to find the letter that was added in t.

class Solution:
     def findTheDifference(self, s, t):
         """
         :type s: str
         :type t: str
         :rtype: str
         """
         sums=sum([ord(i) for i in s]), sum([ord(i) for i in t])
         return chr(sum([ord(i) for i in t])-sum([ord(i) for i in s]))
