int query_sum(int qL, int qR) /// function for finding the sum of values of all element in the range [qL; qR].

* It works under the assumption that T1 and T2 are ordered (all keys in T1 are smaller than keys in T2).

8 июн. 2022 г. · Implicit treap is a simple modification of the regular treap which is a very powerful data structure. In fact, implicit treap can be considered ...

This data structure can fastly insert arbitrary blocks of array to any position and erase them. So it's very similar to implicit cartesian tree.

Note that in an implicit treap, the merge function is largely unchanged because it does not depend on the key. In the split operation we go from the root down, ... Treaps · Splitting · Implicit Treaps · Solution

16 авг. 2010 г. · There's a data structure called treap: that's a randomized binary search tree, which is also a heap on randomly generated so-called priorities.
