Given two List of strings a and b, we need to find the minimum number of manipulations required to make each two strings anagram from the two lists.

Input : 
       a = "a", "jk", "abb", "mn", "abc"…

Given the root of a binary tree, the value of a target node target, and an integer k, return an array of the values of all nodes that have a distance k from the target node.

You can return the answer in any order.

Example 1:

A company has n employees with a unique ID for each employee from 0 to n - 1. The head of the company is the one with headID.

Each employee has one direct manager given in the manager array where manager[i] is the direct manager of the i-th employee, manager[headID]…

Given strings s1 and s2, return the minimum contiguous substring part of s1, so that s2 is a subsequence of the part.

If there is no such window in s1 that covers all characters in s2, return the empty string "". …

We are given a set of documents. Each document is submitted by a different individual. However, we suspect that some individuals may have copied from others. Given a plagiarized submitted document, we want to identify the number of documents with which there is a potential match. We have converted each…

Given an array of positive integers nums and a positive integer target, return the minimal length of a contiguous subarray [numsl, numsl+1, ..., numsr-1, numsr] of which the sum is greater than or equal to target. If there is no such subarray, return 0 instead.

Example 1:

Input: target =…

Input:  arr[] = {1, 3, 6, 10, 11, 15};
Output: 2

Input:  arr[] = {1, 1, 1, 1};
Output: 5

Input:  arr[] = {1, 1, 3, 4};
Output: 10

Input:  arr[] = {1, 2, 5, 10, 20, 40};
Output: 4

Input:  arr[] = {1, 2, 3, 4, 5, 6};
Output…

Given an array of integers arr, you are initially positioned at the first index of the array.

In one step you can jump from an index i to index:

• i + 1 where: i + 1 < arr.length.
• i - 1 where: i - 1 >= 0.
• j where: arr[i]…
