句法: M = max(A) M = max(A,[],dim) [M,I] = max(___) C = max(A,B) ___ = max(___,nanflag)   描述: M=max(A)返回集合A中最大的元素. 如果A是一个向量,则max(A)返回的是集合A的一个元素. 如果A是一个矩阵,则max(A)返回的是包含每列最大值的行向量. 如果A是一个多维数组,则max(A)沿着第一个数组维度运行,其大小不等于1,将元素作为向量进行处理.该维度变为1,而所有其他维度的大小保持不变.如果…

Java program to find the largest element in array Given an array of numbers, write a java program to find the largest element in the given array. Example: int[] a = {1, 5, 3, 9, 2, 8, 2} Largest Element: 9 Java 代码 public class LargestElementInArray {…

參考自: https://love2dev.com/blog/javascript-remove-from-array/ 1. Removing Elements from End of Array var ar = [1, 2, 3, 4, 5, 6]; ar.length = 4; // set length to remove elements console.log( ar ); // [1, 2, 3, 4] var ar = [1, 2, 3, 4, 5, 6]; ar.pop();…

这是一道面试亚马逊时的题目,要求Time O(n). 我刚开始想的是算出所有的数的总product,再去除以对应位置的元素,但这种做法的问题是若该位置为0,就会报错. 到网上搜了下,才知道,原来有这种做法. e.g. arr = {0,1,2,3},生成两个array: upArr = {1,arr[0], arr[0]*arr[1],arr[0]*arr[1]*arr[2]} downArr = {arr[0]*arr[1]*arr[2],arr[1]*arr[2], arr[2],1} 最后…

curry翻译为中文就是咖喱.意为使用curry可以让代码更有味道. scala里的curry化可以把函数从接收多个参数转换成接收多个参数列表.也就是说我们要编写的函数不是只有一个参数列表,这个参数列表中有多个参数以逗号分隔:而是一个函数中有多个参数列表,每个参数列表中只有一个参数(当然,也可以有多个参数).也就是说我们写的函数不再只是这样子的: def foo(a: Int, b: Int, c: Int) {} 而是这样子的:foo(1)(2)(3),或者这样的:foo(1){2}{3},甚…

上一节的函数值只有一个参数.函数值当然也是可以有多个参数的.看一下下面的inject方法: def inject(arr: Array[Int], initial: Int, operation: (Int, Int) => Int): Int = { var carryOver = initial arr.foreach(element => carryOver = operation(carryOver, element)) carryOver } 在inject方法中有三个参数:一个数组…

Recently i was doing some study on algorithms. A classic problem is to find the K largest(smallest) numbers from an array. I mainly studyed two methods, one is directly methold. It is an extension of select sort, always select the largest number from…

Find K-th largest element in an array. Notice You can swap elements in the array Example In array [9,3,2,4,8], the 3rd largest element is 4. In array [1,2,3,4,5], the 1st largest element is 5, 2nd largest element is 4, 3rd largest element is 3 and et…

Find the second max number in a given array. Notice You can assume the array contains at least two numbers.   Example Given [1, 3, 2, 4], return 3. Given [1, 2], return 1. 解法一: public class Solution { /** * @param nums: An integer array. * @return: T…
