题目:Patching Array Given a sorted positive integer array nums and an integer n, add/patch elements to the array such that any number in range [1, n]inclusive can be formed by the sum of some elements in the array. Return the minimum number of patches
https://leetcode.com/problems/k-diff-pairs-in-an-array/#/description Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array. Here a k-diff pair is defined as an integer pair (i, j), where i and j
通常情况下.我们在使用数组(Array)或字典(Dictionary)时会使用到下标.事实上在Swift中.我们还能够给类.结构.枚举等自己定义下标(subscript). 一.基本使用 struct TimesTable { let multiplier: Int subscript(index: Int) -> Int { return multiplier * index } } 我在TimesTable这个结构中自己定义了一个subscript.而且这个subscript类似于方法,看上
Description Vasya has an array a consisting of positive integer numbers. Vasya wants to divide this array into two non-empty consecutive parts (the prefix and the suffix) so that the sum of all elements in the first part equals to the sum of elements
Given a sorted array of integers nums and integer values a, b and c. Apply a function of the form f(x) = ax2 + bx + c to each element x in the array. The returned array must be in sorted order. Expected time complexity: O(n) Example: nums = [-4, -2,
题目: Implement atoi to convert a string to an integer.Hint: Carefully consider all possible input cases. 官方难度: Easy 翻译: 实现atoi算法,将一个字符串转成整数. 提示:仔细考虑各种可能情况. 补充资料: atoi函数是C语言库中的一个函数,百度了一下其实现的功能如下: Requirements for atoi:1.The function first discards as m
