Given two integers dividend and divisor, divide two integers without using multiplication, division, and mod operator.
The integer division should truncate toward zero, which means losing its fractional part. For example, 8.345 would be truncated to 8, and -2.7335 would be truncated to -2.
Return *the quotient after dividing dividend by *divisor.
**Note: **Assume we are dealing with an environment that could only store integers within the 32-bit signed integer range: [−2<sup>31</sup>, 2<sup>31</sup><span> </span>− 1]. For this problem, if the quotient is strictly greater than2<sup>31</sup><span> </span>- 1, then return 2<sup>31</sup><span> </span>- 1, and if the quotient is strictly less than-2<sup>31</sup>, then return -2<sup>31</sup>.
Given a string array words, return the maximum value oflength(word[i]) * length(word[j])where the two words do not share common letters. If no such two words exist, return 0.
As the ruler of a kingdom, you have an army of wizards at your command.
You are given a 0-indexed integer array strength, where strength[i] denotes the strength of the i<sup>th</sup> wizard. For a contiguous group of wizards (i.e. the wizards’ strengths form a subarray of strength), the total strength is defined as the product of the following two values:
The strength of the weakest wizard in the group.
The total of all the individual strengths of the wizards in the group.
Return the sum of the total strengths of all contiguous groups of wizards. Since the answer may be very large, return it modulo10<sup>9</sup><span> </span>+ 7.
A subarray is a contiguous non-empty sequence of elements within an array.
You are given a 2D integer array stockPrices where stockPrices[i] = [day<sub>i</sub>, price<sub>i</sub>] indicates the price of the stock on day day<sub>i</sub> is price<sub>i</sub>. A line chart is created from the array by plotting the points on an XY plane with the X-axis representing the day and the Y-axis representing the price and connecting adjacent points. One such example is shown below:
You have n bags numbered from 0 to n - 1. You are given two 0-indexed integer arrays capacity and rocks. The i<sup>th</sup> bag can hold a maximum of capacity[i] rocks and currently contains rocks[i] rocks. You are also given an integer additionalRocks, the number of additional rocks you can place in any of the bags.
Return* the maximum number of bags that could have full capacity after placing the additional rocks in some bags.*
You are given an m x n integer array grid. There is a robot initially located at the top-left corner (i.e., grid[0][0]). The robot tries to move to the bottom-right corner (i.e., grid[m-1][n-1]). The robot can only move either down or right at any point in time.
An obstacle and space are marked as 1 or 0 respectively in grid. A path that the robot takes cannot include any square that is an obstacle.
Return the number of possible unique paths that the robot can take to reach the bottom-right corner.
The testcases are generated so that the answer will be less than or equal to 2 * 10<sup>9</sup>.
Given an m x n integers matrix, return *the length of the longest increasing path in *matrix.
From each cell, you can either move in four directions: left, right, up, or down. You may not move diagonally or move outside the boundary (i.e., wrap-around is not allowed).
