You are a given a unimodal array of n distinct elements, meaning that its entries are in increasing order up until its maximum element, after which its elements are in decreasing order. Give an algorithm to compute the maximum element that runs in O(log n) time. 输入格式: An integer n ...
mask=mask| 1<<i mask得到第i位是1的数; 第一轮mask是 100000, 第二轮 11000 第三轮 1110000 ... forAi in A 对数组的每个元素存储第i位 Ai & 1< hash 存入hash forhi in hash ifmax ^ hi in hash 我们要求 a ^ b = 最大数, 反过来这里判断 最大数 ^ a 是否存在于hash 更新max值 好了 ...
https://leetcode.com/problems/maximum-xor-of-two-numbers-in-an-array/description/ 解题方法: 在解题之前,首先要了解2个事情: 两个数XOR的结果取决于这两位数的二进制形式每一位是否相同。当相同时,结果在这一位上为0;当不同时,结果在这一位上为1。 假设我们有3个数:a, b, c;当a 和 b以及b和c...
Given an arrayA, find the two numbersa,binAthat makesa * b == 1223. 我们可能首先想这么写 fori inrange(len(nums)):forj inrange(i+1,len(nums)):ifnums[i]*nums[j]==1223:returnTrue 但是我们想一下,其实可以优化位O(n), 用一个set就行了 set_=set(nums)fornuminnums:if1223// num ...
Given anon-emptyarray of numbers, a0, a1, a2, … , an-1, where 0 ≤ ai< 231. Find the maximum result of aiXOR aj, where 0 ≤i,j<n. Could you do this in O(n) runtime? Example: Input: [3, 10, 5, 25, 2, 8]
If the number-of-elements operand has the value zero, no elements are searched; %MAXARR and %MINARR return the value zero. If an alternate collating sequence is in effect for an alphanumeric array, the alternate collating sequence is used unless ALTSEQ(*NONE) is specified for the array...

Write a program in C to find the maximum and minimum elements in an array.The task involves writing a C program to find and display the maximum and minimum elements in an array. The program will take a specified number of integer inputs, store them in an array, and then determine and ...
NumPymaximum()function is used to get a new array that contains element-wise maximum values of two arrays. It compares two arrays and returns a new array containing the maximum values. If one of the elements being compared isNaN(Not a Number), the result for that pair is alsoNaN. Similar...
