One nauseating thing is that @angular/cli generated projects do not support IE well by default, and neither does 9/10/11. The good news is that @angular/cli generates the polyfill.ts file by default, which can be supported in a few simple steps. Step 1: Create a project with @angular/cli ng new ie-test cd ie-test ng ser ...

Version 7.2 of PHP replaces mcrypt_encrypt with openssl_encrypt, which makes the Aes encryption classes written by ourselves useless. The client side of this project used AES-128-ECB encryption, and I used online AES tools to test, and found that the encryption and decryption methods I wrote had different values. The key encrypted is not 16 bi ...

Title Description There are n floors, each floor has m districts, which need to go up and down stairs or elevators. It takes a unit time to move and climb a staircase between adjacent areas. The maximum speed of elevators is v floors per unit time. Now, what is the minimum time needed to move from y1 district on x1 floor to y2 ...

Problem Description There are n apples on a tree, numbered from 1 to n. Count the number of ways to pick at most m apples.   Input The first line of the input contains an integer T (1≤T≤105) denoting the number of test cases. Each test case consists of one line with two integers n,m (1≤m≤n≤105).   Output For each test ca ...

Title Link Problem meaning: n numbers, through an algorithm and generators X,Y,Z to generate m group updates. Each time, the number less than V in [l,r][l,r] is updated to v. The values of (1 a[1]) (2 a[2] (n a[n])(1 a[1]) (2 a[2] (n a[n]) after m updates are calculated. Among them, The main contradiction in the topic is to ...

Title Link This is the link Description T. Chur teaches various groups of students at university U. Every U-student has a unique Student Identification Number (SIN). A SIN s is an integer in the range 0 ≤ s ≤ MaxSIN with MaxSIN = 106-1. T. Chur finds this range of SINs too large for identification within her groups. For each ...

    Here's the general idea: Give you an n*m matrix of 01. Now let's get rid of a number for each row and column, and ask that the absolute value of the position of the number removed between adjacent rows be less than or equal to k. Now ask you how many kinds of rectangles you can delete. First of all, let's consider on ...
