algorithm

问题 The hypot function, introduced into C in the 1999 revision of the language, calculates the hypotenuse of a right triangle given the other sides as arguments, but with care taken to avoid the over/underflow which would result from the naive implementation as double hypot(double a, double b) { return sqrt(a*a + b*b); } I find myself with the need for companion functionality: given a side and the hypotenuse of a triangle, find the third side (avoiding under/overflow). I can think of a few ways

问题 I'm not sure what sort of algorithm to apply here. My thoughts are that I should go about finding all the unique values first and then from there I should grab the minimum. However, I'm not sure how to implement this. I'm trying to do this in C. The only constraints are that I can only use #include <stdio.h> #include <string.h> . 回答1: Using the algorithm you propose in your question (i.e. to first find all unique values and then find the lowest one), a possible implementation looks like this:

问题 This question already has answers here : Generating random results by weight in PHP? (12 answers) Closed 7 years ago . I want to select a number randomly, but based on probability from a group of numbers; for example (2-6). I'd like the following distribution: 6's probability should be 10% 5's probability should be 40% 4's probability should be 35% 3's probability should be 5% 2's probability should be 5% 回答1: The best you can do is generate a number between 0 and 100, and see in what range

问题 The main goal of this algorithm is to find similar titles of news articles from different sources of web and group them, let's say above 55.55% similarity. My current approach of the algorithm consist of following steps: Feed data from MYSQL database into a two-dimensional array ex. $arrayOne . Make another copy of that array into ex. $arrayTwo . Create a clean array which will only contain similar titles and other content ex. $array_smlr . Loop, foreach $arrayOne article_title check for

问题 It's showing the wrong answer. Can anybody please tell me which test case I am missing ? Without Adjacent Given an array arr[] of N positive integers. The task is to find a subsequence with maximum sum such that there should be no adjacent elements from the array in the subsequence. Input: First line of input contains number of testcases T. For each testcase, first line of input contains size of array N. Next line contains N elements of the array space seperated. Output: For each testcase,
