Graph structure Exercise--judging whether a given graph has a valid topological sequence Time limit:1000ms Memory limit:65536k The topic describes whether there is a valid topological sequence for a given graph to determine if there is one. The input input contains multiple groups, each set in the following format. The first line contains two integer n,m that represent the number of vertices and sides of the graph.(n1 02 21) 22 1Sampl

1026:c Language Programming Tutorial (third Edition) After class exercise 7.4 The topic describes an array of 9 elements that have already been sorted, and entering a number now requires that it be inserted into the array in the same order as it was originally ordered. Enter the first line, the original sequence. The second line, the number that needs to be inserted. Output sorted sequence sample input1 7 8 17 23 24 59 62 10150Sample output17817232450

Eighth Chapter8-6. Decomposition of the element factor. Write a function based on the IsPrime () and getfactors () functions in the previous exercise, which takes an integer as a parameter and returns a list of all prime factors for that integer type. This process is called the decomposition of the element factor, and the product of all the factors it outputs should be the original number. Note that there may be duplicate elements in the list. For exa

The nightingale rose diagram is amazing in conventional charts, but I didn't understand it at the beginning. It turns out that nightingale is so great and really worthy of respect. After carefully studying the structure of the image, we found that the original bar chart is represented by the radius of the slice chart. Of course, there are many variants, This is just what I understand. After knowing the structure of slice, the slice angle is determined based on the number of input parameters, and

road, it is common to run a dozen kilometers. At first, I thought it was caused by calcium deficiency. After drinking beef bone marrow soup, I made up calcium for a while, but it didn't improve much. Later I learned that most knee pain is caused by Primary Osteoarthritis caused by the aging of the knee joint itself. The occurrence and recurrence of knee pain are also related to factors such as poor blood circulation, fatigue transition, poor posture, and cold and humid weather.ProgramBoth dev
