The state space of search questions is usually non-linear. For example, the example mentioned above: find a subset of an array. The state space here is actually various combinations of arrays. For this problem, a feasible way to divide the state space is: ...
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] ...
will give you the first cell, it is a cell array of strings with only one element, hence its length of 1. However, you want the content of the first cell. You use curly braces for that: Words{1} This returns you want to know the length of. ...
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...

Have you noticed that you essentially implemented the logic for creating a deep copy of the DataFile? Wouldn’t it be more straightforward to directly call copy.deepcopy() and let Python handle the details? Well, why don’t you find out: Python >>> with DataFile("person.json") as data...
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. ...
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 ...
