Here,we will learn how to define a Macro that will take arguments to find maximum of two numbers? Here is the Macro #define MAX(x,y) ((x>y)?x:y) Here,MAXis the Macro namexandyare the arguments. When program will compile, actual arguments which will be passed into theMAXMacro. ...

Given a non-empty array of numbers, a0, a1, a2, … , an-1, where 0 ≤ ai < 231. Find the maximum result of ai XOR aj, where 0 ≤ i, j < n. Could you do this in O(n) runtime? Example: Input: [3, 10, 5, 25, 2, 8] Output: 28 Explanation: The maximum result is ...
leetcode 421.Maximum XOR of Two Numbers in an Array 题目中给定若干个数,然后任意选定两个数使得其异或值最大。 先利用样例中的: 3 10 5 25 2 8 这些数转换为二进制来看的话那么是先找到最高位的1然后与数组中其他的数相与后的数值保存到set中去,然后利用性质: a^b=c则a^c=b,在set中只要有异或...
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。

Non-point source modeling is uncertain. We shouldn't get caught up in the numbers but move ahead to the water quality goals. The knowledge, quantitative tools and models are accurate, but what we need is intense data collection to support calibration and verification. ...
