Youmust have heard the nameKernighanAndRitchie, The authorsThe C Programming Language. While coding inC, We use differentcontrol statements and loops, such,If-then-Else,For,Do-while, Etc. Consider the following fragment of pseudo code:
// Execution starts here
Do {
U;
V;
} While (Condition);
W;
Inthe above code, there is a bias in each conditional branch. Such codes can berepresented by control flow graphs like below:
Letthe probability of jump

A flowchart with nodes is shown. The probability of entering the next process is equal. Q queries are performed to find the execution expectation of each query node.
Idea: Gaussian deyuan. The expectation of each node is equal to the sum of expectation/exit of all the frontend nodes. Due to the infinite loop, it is not possible to directly recursion, use Gaussian deyuan to determine that the

Test instructions: Starting from 1 each time the equal probability from one point to the point of his neighbor has to go to not go stop seeking to stop the expectation of each point
