You are given a 0-indexed m x n integer matrix grid. The width of a column is determined by the length of its longest integer. For example, the length of an integer is defined as the number of digits in its absolute value, with an additional digit for negative numbers. For each column, return its width, which is the maximum length of any integer in that column.
Given a binary matrix of size m x n, your task is to find the row that contains the highest number of 1’s. If there are multiple rows with the same count of 1’s, return the row with the smallest index. The output should contain the index of the row and the count of 1’s in that row.
You are given two integer arrays, ’nums’ and ‘divisors’. For each element in ‘divisors’, you need to calculate the divisibility score, which is the number of elements in ’nums’ divisible by that divisor. Your goal is to return the divisor with the highest divisibility score. If multiple divisors have the same score, return the smallest one.
You are given two integers: ‘arrivalTime’, representing the scheduled arrival time of a train in hours (in 24-hour format), and ‘delayedTime’, representing the delay in hours. Your task is to compute the time at which the train will actually arrive at the station, taking into account the delay.
You are given a 0-indexed array of positive integers ’nums’ and an integer ‘k’. You need to perform the following operation exactly k times to maximize your score: Select an element from nums, remove it from the array, and add a new element with a value one greater than the selected element. The score is increased by the value of the selected element. Your task is to return the maximum score you can achieve after performing the operation exactly k times.
