Commonly used indicators and statistical methods. Specifically: Tree depth and subtree size DFS sequence of the graph Topological order of graph Connectivity components of the graph The content of the next section will be first published in "91 Tianxue Algorithm". Those who want to participate can...
Then, FF can choose a continuous subsequence from it(for example the subsequence from the third to the fifth integer inclusively). After that, FF will ask TT what the sum of the subsequence he chose is. The next, TT will answer FF's question. Then, FF can redo this process. In the ...
Given the arraynums, for eachnums[i]find out how many numbers in the array are smaller than it. That is, for eachnums[i]you have to count the number of validj'ssuch thatj != iandnums[j] < nums[i]. Return the answer in an array. Example 1: Input: nums = [8,1,2,2,3] ...

I had no inkling of $.global.evt and couldn't find it in the docs. What is it? The single active event of any type? You've also shown me that you can pass a File to the app.eventlisteners.add method! It is documented but I've never noticed. Is that the reason that a...
And if you don't simulate all the possibilities, but go straight to an optimal solution, it is a greedy algorithm. That's right, dynamic programming is to find the optimal solution from the beginning. But sometimes the way you can find something else the total number of other programs, th...
All subsequence errors from other child tasks will be ignored. When a child task throws an error, all of the remaining child tasks (child tasks that are still running) will be marked as canceled. A child task marked as canceled will continue to execute until we explicitly stop it. A ...
1) make array b such that b consists only of those elements a[i] such that a[i] > i — 1, preserving order of course. 2) find LIS (longest increasing subsequence of b) in O(NlogN) time (it's easily googlable). 3) answer is N — LIS. N here is length of array a. ...
More robust relations and time-lock encryption for long time periods The longer the time between encryption and decryption of a ciphertext is, the more difficult it becomes to find a suitable target bound function \(\delta \). One could, however, instead use relations which are more “robust...
