If two positive integers a , b are given, find the least positive integer n satisfying the condition a × S ( n ) = b × S ( 2 n ) . If there is no such number then output 0. Input The first line contains the number of test caces T ( T ≤ 10 ) . The next T lines contain two positive integers a , b ( 0 < a , b < 101 ) . Output Output the answer in a new line for each

Each grid (i,j)(0 ≤ i < N, 0 ≤ j < M) is painted in white at first. Then we perform q operations: For each operation, we are given (x c , y c ) and r. We will paint all grids (i, j) that meets to black. You need to calculate the number of white grids left in matrix A. 输入描述: The first line of the input is T(1≤ T ≤ 40), which stands for the number of test cases you need to

Description: The elderly aunts always like to look for bargains and preferential merchandise. Now there is a shop carrying out group purchase promotion. Rules are as follows : There are r pieces of promotional items, and each item is only one. In the group purchase, everyone will buy one at least and have to conform the rules if they want to enjoy the benefit : All the merchandise at a prime number has to be purchased ; the merchandise at non-prime number cannot be chosen ; The amount of money that each person pays is the square of the difference between the maximum and minimum value of the

  A number of K balls are dropped one by one from the root of a fully binary tree structure FBT. Each time the ball being dropped first visits a non-terminal node. It then keeps moving down, either follows the path of the left subtree, or follows the path of the right subtree, until it stops at one of the leaf nodes of FBT. To determine a ball’s moving direction a flag is set up in every non-terminal node with two values, either false or true . Initially, all of the flags are false . When visiting a non-terminal node if the flag’s current value at this node is false , then the ball will first

Software development has already undergone an important journey from its beginnings to test automation and continuous testing. As time progresses, however, it is certain that testing will have to evolve as well. With digital transformations and the drive towards DevOps, automated testing is now at the heart of software testing and has taken the lead in the development process. 软件的发展从开始到自动化测试和持续测试已经走过了一个重要的旅程。时间的流逝，测试也会同样的演变是毋庸置疑的。随着数据的变革和开发运维驱动，自动化测试现在已经是软件测试的核心，并且在发展的进程中处于领先地位。 Artificial Intelligence (AI) seems to be the future of testing. AI has created high hopes in software testing and

此次比赛，我很荣幸得此机会跟着学长学姐去打铁。第一次接触这种比赛，确实感到新奇，同时也有不安，因为平时没好好做题，知之甚少，基础确实是超级不稳的。好在学长说让我们开阔一下眼界，尽力就行。比赛做出几个题我就不说了，但是补题的时候真的发现我们真的很菜，简单的题我们竟然可以耗时那么久。。。。。emmm，，以后可得努力了 A - Calandar On a planet far away from Earth, one year is composed of 12 months, and each month always consists of 30 days. Also on that planet, there are 5 days in a week, which are Monday, Tuesday, Wednesday, Thursday and Friday. That is to say, if today is Monday, then tomorrow will be Tuesday, the day after tomorrow will be Wednesday. After 3 days it will be Thursday, after 4 days it will be Friday, and after 5 days it will again be

轻轻松松也能拿到区域赛名额，CCPC真的好难 An Olympian Math Problem 问答 只看题面 54.76% 1000ms 65536K Alice, a student of grade 6 6, is thinking about an Olympian Math problem, but she feels so despair that she cries. And her classmate, Bob, has no idea about the problem. Thus he wants you to help him. The problem is: We denote k! k !: k! = 1 \times 2 \times \cdots \times (k - 1) \times k k ! = 1 × 2 × ⋯ × ( k − 1 ) × k We denote S S: S = 1 \times 1! + 2 \times 2! + \cdots + S = 1 × 1 ! + 2 × 2 ! + ⋯ + (n - 1) \times (n-1)! ( n − 1 ) × ( n − 1 ) ! Then S S module n n is ____________ You are given an integer n n. You
