Python找出列表中数字的最大值和最小值 思路: 先使用冒泡排序将列表中的数字从小到大依次排序 取出数组首元素和尾元素 运行结果: 源代码: 1 ''' 2 4.编写函数,功能:找出多个数中的最大值与最小值. 3 ''' 4 def findNumValue(list=[]): 5 for i in range(len(list)-1): 6 for j in range(len(list)-1-i): 7 if list[j]>list[j+1]: 8 temp=list[j] 9 list
Given an array of integers, 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements that appear twice in this array. Could you do it without extra space and in O(n) runtime? Example: Input: [4,3,2,7,
方法一: 元素两两比较,如果有数据不同,则r的值变为false #!/usr/bin/python a=[22,22,22,22] b = len(a) r=True for i in range(b): if i ==(b-1): break if a[i] == a[i+1]: continue else: r=False print(r) 方法二: 数据去重,如果去重后列表中的元素大于1,则说明数据重复 #!/usr/bin/python a=[22,22,22,222] b=len(se
import java.util.Arrays; /** * Created by ccc on 16-4-27. */ public class Test { public static void main(String arg[]) { , , }; ,,,, , }; Arrays.sort(a); Arrays.sort(b); int len = a.length; ; i < len; i++) { ) { System.out.println(b[i]); } } } } Arra
镇场诗: 诚听如来语,顿舍世间名与利.愿做地藏徒,广演是经阎浮提. 愿尽吾所学,成就一良心博客.愿诸后来人,重现智慧清净体.------------------------------------------code: num=[1,2,3,4,5,6,6,7,8] res=[] for each in num : if each not in res : res.append(each) print(res) #有趣有趣,这么写基础的机制与方法,可以写出如此优美的函数 #小甲鱼 强悍 resu
［抄题］: Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Example 1: Input: [1,3

Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime?
