535. Encode and Decode TinyURL

Note: This is a companion problem to the System Design problem: Design TinyURL.
TinyURL is a URL shortening service where you enter a URL such as https://leetcode.com/problems/design-tinyurl and it returns a short URL such as http://tinyurl.com/4e9iAk.
Design the encode and decode methods for the TinyURL service. There is no restriction on how your encode/decode algorithm should work. You just need to ensure that a URL can be encoded to a tiny URL and the tiny URL can be decoded to the original URL.

Python 3 code:

class Codec:

    def encode(self, longUrl):
        """Encodes a URL to a shortened URL.
        
        :type longUrl: str
        :rtype: str
        """
        return longUrl

    def decode(self, shortUrl):
        """Decodes a shortened URL to its original URL.
        
        :type shortUrl: str
        :rtype: str
        """
        return shortUrl

# Your Codec object will be instantiated and called as such:
# codec = Codec()
# codec.decode(codec.encode(url))

561. Array Partition I

Given an array of  2n  integers, your task is to group these integers into  n  pairs of integer, say (a 1 , b 1 ), (a 2 , b 2 ), ..., (a n , b n ) which makes sum of min(a i , b i ) for all i from 1 to n as large as possible. Example 1: Input: [1,4,3,2] Output: 4 Explanation: n is 2, and the maximum sum of pairs is 4 = min(1, 2) + min(3, 4). Note: n  is a positive integer, which is in the range of [1, 10000]. All the integers in the array will be in the range of [-10000, 10000]. Python 3 Code: class Solution:     def arrayPairSum(self, nums):         """         :type nums: List[int]         :rtype: int         """         nums.sort()         x = 0         for i in range (0,len(nums),2):             x += nums[i]         ret...

771. Jewels and Stones

You're given strings  J  representing the types of stones that are jewels, and  S  representing the stones you have.  Each character in  S is a type of stone you have.  You want to know how many of the stones you have are also jewels. The letters in  J  are guaranteed distinct, and all characters in  J  and  S  are letters. Letters are case sensitive, so  "a"  is considered a different type of stone from  "A" . Example 1: Input: J = "aA", S = "aAAbbbb" Output: 3 Example 2: Input: J = "z", S = "ZZ" Output: 0 Note: S  and  J  will consist of letters and have length at most 50. The characters in  J  are distinct. Code: class Solution:     def numJewelsInStones(self, J, S):         """         :type J: str         :type S: str         :rtype: int   ...

461. Hamming Distance

The  Hamming distance  between two integers is the number of positions at which the corresponding bits are different. Given two integers  x  and  y , calculate the Hamming distance. Note: 0 ≤  x ,  y  < 2 31 . Example: Input: x = 1, y = 4 Output: 2 Explanation: 1 (0 0 0 1) 4 (0 1 0 0) ↑ ↑ The above arrows point to positions where the corresponding bits are different. Python 3 Code: class Solution:     def hammingDistance(self, x, y):         """         :type x: int         :type y: int         :rtype: int         """         z = int (x ^ y)         ans = 0         while z > 0:             ans += z % 2             z = z >> 1      ...
