Container with Most Water - Leetcode 11 - Python

 You are given an integer array height of length n. There are n vertical lines drawn such that the two endpoints of the ith line are (i, 0) and (i, height[i]).

Find two lines that together with the x-axis form a container, such that the container contains the most water.

Return the maximum amount of water a container can store.

Notice that you may not slant the container.


 Input: height = [1,8,6,2,5,4,8,3,7]

Output: 49
Explanation: The above vertical lines are represented by array [1,8,6,2,5,4,8,3,7]. In this case, the max area of water (blue section) the container can contain is 49.


class Solution:

    def maxArea(self, height: List[int]) -> int:

        # ans = 0

        # for l in range(len(height)):

        #     for r in range(l+1, len(height)):

        #         ar = (r-l) * min(height[l],height[r])

        #         ans = max(ans, ar)

        # return ans

        

        ans = 0

        l, r = 0, len(height)-1

        

        while l<r:

            ar = (r-l) * min(height[l],height[r])

            ans = max(ans, ar)

            

            if height[l] < height[r]:

                l+=1

            else :

                r -=1

        return ans

Leetcode 424. Longest Repeating Character Replacement. Python (Sliding Window)

  424 .  Longest Repeating Character Replacement You are given a string  s  and an integer  k . You can choose any character of the string and change it to any other uppercase English character. You can perform this operation at most  k  times. Return  the length of the longest substring containing the same letter you can get after performing the above operations .   Example 1: Input: s = "ABAB", k = 2 Output: 4 Explanation: Replace the two 'A's with two 'B's or vice versa. Example 2: Input: s = "AABABBA", k = 1 Output: 4 Explanation: Replace the one 'A' in the middle with 'B' and form "AABBBBA". The substring "BBBB" has the longest repeating letters, which is 4.   Constraints: 1 <= s.length <= 10 5 s  consists of only uppercase English letters. 0 <= k <= s.length Solution :  class Solution: def characterReplacement(self, s: str, k: int) -> int: hm = {} ans = 0 ...

Leetcode 371. Sum of Two Integers. C++ / Java

371 .  Sum of Two Integers   Given two integers  a  and  b , return  the sum of the two integers without using the operators   +   and   - .   Example 1: Input: a = 1, b = 2 Output: 3 Example 2: Input: a = 2, b = 3 Output: 5   Constraints: -1000 <= a, b <= 1000 Solution :  C++ : class Solution { public: int getSum(int a, int b) { if (b==0) return a; int sum = a ^ b; int cr = (unsigned int) (a & b) << 1; return getSum(sum, cr); } }; Java :  class Solution { public int getSum(int a, int b) { while(b != 0){ int tmp = (a & b) << 1; a = a ^ b; b = tmp; } return a; } } Explaination :

Two Sum - Leetcode 1 - HashMap - Python

1. Two Sum Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order class Solution:     def twoSum(self, nums: List[int], target: int) -> List[int]:         hashmap = {} #  val : index                  for i,n in enumerate(nums):             diff = target - n             if diff in hashmap:                 return [hashmap[diff],i]             hashmap[n]=i         return Explained :
