Let's suppose there is the following query:
```
SELECT keys..., aggregates... FROM table
GROUP BY keys... ORDER BY expr LIMIT n
```
If the `expr` in the ORDER BY depends only on the GROUP BY…

It's a pretty common problem (and we have this problem :)) where you want a priority queue that "loses" items of lesser priority (has a max size). What do you think of extending heap?

Great work on completing these challenges. Here's some feedback to improve your code:
- Try writing some tests for priority queues, or even just creating a simple priority queue at the bottom of your…

## Description
On a cluster (3.4.2) of 6 nodes that has a fairly large amount of databases (~1500 of size between 1GB and 150GB each), we have recently added and modified about 20 design docs per d…

В стандарте есть свободные функции для работы с heap структурой данных: make_heap, push_heap, pop_heap.
Предлагаю добавить класс с необходимом набором методов для работы со структурой, как например…

Hey @DhanushNehru,
I want to implement the Dijkstra's Algorithm in Python.
Dijkstra's algorithm is a greedy algorithm that finds the shortest paths in a graph with non-negative edge weights by fol…

This proposal is for use with #43651. I propose to add a parameterized `Heap` type to the `container/heap` package. For the typical usage of `container/heap` where the heap is backed by a slice, using…

Same interface as `mut-priority-queue`, but using a heap instead. See if performance is better than `mut-priority-queue`.

Heya,
Sorry if this is a non-issue, but as there are some error entries in OneLauncher's log, I thought I'd post it here. Today I had numerous lock-ups that made the game unplayable. I haven't chan…
