subtract 1. Now the numbers is 0, 0, 2. Now she subtracts 2 from 2 and all the numbers become 0.Dexter is isn't so dumb to understand the This can be do very easily, so-make a twist he'll give a limit L for each N and surely L'll be as minimum as possible so it's still possible to win within L moves. But Dexter does not has time to think how to determine L for each n, so he asks you to write a code which would take N as Input and give L as output.Input and Output:Input consists of several lines

InputInput starts with an integerT( +), denoting the number of test cases. Each case starts with a line containing an integerN(1N).OutputFor each case, print the case number and the number of ways the race can finish.

Tip 2-15: Under Windows, enter after the completion of the input key, and then press CTRL + Z, and finally press ENTER key, you can end the input. Under Linux, you can end the input by pressing the CTRL+D key when you have finished typing.Two ways to work with files include: Freopen and fopen.Freopen WayThe simplest way to use a file is to use input-output redirection, by simply adding the following two statements at the entrance of the main function:Freopen ("input.txt""R", stdin); Freopen ("

When participating in programming contests, you sometimes face the following problem: You know how to calcutale the output for the given input values, but your algorithm is way too slow to ever pass the time limit. however hard you try, you just can't discover the proper break-o condition conditions that wocould bring down the number of iterations to within acceptable limits. now if the range of input values Is not too big, th
scanf is correctly read, the return value is equal to the number of variables read. The scanf function returns 1 when the read error occurs and the end of the file is read.while (scanf("%d", cnt) != -1)The maximum range of input data is 10000,10000 cubic is 10^12, and the maximum value of type int is 2147483647, approximately 2*10^9, far exceeds the maximum value of int, so overflow occurs during the calculation, which results in an error. So we need to use a larger integer type long long, whic

An AVL tree is a self-balancing binary search tree. In a AVL tree, the heights of the "two child subtrees of" any node differ by at most one; If at any time they differ by the more than one, the rebalancing is do to restore the property. Figures 1-4 illustrate the rotation rules.
Now given a sequence of insertions, your are supposed to tell the root of the resulting AVL tree.

The lookup plugin for ansible can be used to read information from external data and then pay a variable. The types of external data information obtained include reading the contents of a file, randomly generating password, executing shell commands, reading Redis key values, and so on. Note that all of the operations of lookup are done on the Ansible console, not on the remote target machine.
Example:
----hosts:test_server remote_user:root tasks:-Name: Get normal file content (files are present
, you need to solve all of its specific cases. Try solving some (or multiple) specific cases and then try and generalize them to the solution of the main problem. Such specific cases can be regarded as the simplifications of the problem, i.e. we can reason by the following principle: "If I don ' t know how to solve a complex problem, I think I ' ll simplify it and find the solutions of the simplified version ".The popular examples of simplifications (specific cases):
