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.
Solution:
func findTheDifference(s string, t string) byte {
bs := byte(0)
for i:=0; i < len(s); i++ {
bs = (bs ^ s[i])
}
for i:=0; i < len(t); i++ {
bs = (bs ^ t[i])
}
return bs
}
