LeetCode #389
Q.
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.
Process
// Process
//1. Input string s , t
//2. Iterate s
// 2.1. Make dynamic s case
//3. Iterate t
// 3.1. Make dynamic t case
//4. Iterate dynamic cases
// 4.1. compare number
//5. Return result
// 처리과정
//1. 스트링 s, t 입력받는다.
//2. 스트링 s 반복한다.
// 2.1. s 동적 판 만든다.
//3. 스트링 t 반복한다.
// 3.1. t dynamic 판 만든다
//4. 동적판 반복한다
// 4.1. 다른수가 있는지 확인한다.
//5. 결과 반환한다.
Code.. lemme see example code!!!
코드.. 예제코드를 보자!!!
