Algorithm written test surface Test _ Mall engage in activities, full 100 minus 30, full 200 minus 80, ask 1000 yuan the most can buy what money?Solution Ideas:1, first spend 1000 yuan, return (1000/200) *80 = 4002, spend 400 yuan, return (400/200) *80 = 160;3, borrow someone else 40 yuan, hand gather enough 200 yuan, return 80 yuan.4, also give others 40 yuan, h

Recently work relatively busy, and busy and forget, so record ideas and methods, do not understand can give me a message.First request data parameterization, you can do a CSV file rows of data, you can also write separately, the purpose of the separate writing is to follow the random collocation, so that it is more consistent with the algorithm test (to cover as far as possible)View in view results tree after executionUse regular to extract the requir

This framework provides an extension interface for different execution platforms, only implemented under Windows.Supports script recording. Script playback. Test logs.Now WP basically few people develop the application. This code can actually be slightly modified to test other Windows programs.GitHub Address: Https://github.com/csusheep/mouse_recorder.gitRecording:Open the WP7 simulator,Run recording script

A very simple test question of gele electronics is wrong !!!, Incorrect written test Open the question picture and you will be able to see it. Void main (void) {Union unt {Unsigned char uc [4]; Unsigned int ui;}; Union unt t; T. ui = 0x12345678; Printf ("% d \ n", t. uc [1]);} The Community is rarely used in embedded development, so I didn't take a closer look

Donghua software test, Donghua written test 1. switch statement execution process: starting from the first matching condition, all the code behind it is executed until it is completed or break is encountered; #includeOutput result: 2 1 2. logic operator operation rules: A B judge B when A is true. When A is false, the final result is false; A | B determines B

, according to their own thinking to writeI know the problem.

After several C-language written examinations, it is often asked to ask for the first 100 of the 10,000 numbers, and now think of two ways to solve:Method 1:1-dimensional valuesThe code is as follows:#include #include #include #include To find the maximum value of the array, return B "0"int max (int b[],int N){int i,t,k=0,m=0;int c=n;The array 22 is compared and the larger value iswhile (n!=1){for (i=0;i{if (b[i]>b[i+1]){t=0;T=b[i];B[I]=B[I/2];b[i/2]=

some time ago because to participate in a written test, during the preparation of the online found two articles on the written topic, one of the In the process of finding these answers, I recorded the relevant answers and formed the following things. Need to explain that the following answer must have a lot of incomplete or even wrong place, need you to correct a

Today took part in the written examination of IBM IT Specialist trainee .... I'm really tired of it, it's all in English. I read the title of the time is exactly equal to the time to answer the question, so nothing to do with the same ... The first part of the Englist test, and three small, the first part is English listening, the second part is the grammar, words, reading comprehension, the third part un

Java Written test Bank (05 issue) Whether the 1,volatile keyword guarantees thread safety. （） Answer: No The volatile keyword is used in multithreaded synchronization to ensure read visibility, and the JVM simply guarantees that the value from main memory load to thread working memory is the most recent read value, not the cache. However, thread safety is not guaranteed by multiple threads writing to vola

can have multiple levels and references can be only one level5.sizeof refers to the size of the pointed variable, and the sizeof pointer gets the size of the pointer itself.6. When the pointer is passed as a function parameter, the copy of the argument is passed to the formal parameter, such as the following program (a), the reference is passed as a function parameter instead of the copy, and the reference is a true share of the same inner deposit element.Program (a):#include #include #include
