kandi X-RAY | allpairs Summary
AllPairs test combinations generator. AllPairs is an open source test combinations generator written in Python, developed and maintained by MetaCommunications Engineering. The generator allows one to create a set of tests using "pairwise combinations" method, reducing a number of combinations of variables into a lesser set that covers most situations. For more info on pairwise testing see The easiest way to get started is to check out usage examples in the "examples" directory and online at

I was going through uniswap code trying to understand the code and most of it is pretty clear but I do have a few questions.
in this function:
...ANSWER
Answered 2022-Feb-15 at 09:15It makes use of the create2
opcode allowing you to deploy a contract to an address determinable by its bytecode and salt.
Uniswap V2 was written in Solidity 0.5 that didn't have a way to produce the create2
opcode directly from the language. So you had to use a low-lewel assemly to actually use this opcode.
The current version 0.8 allows passing the salt
param producing the create2
(instead of the regular create
) opcode.

...ANSWER
Answered 2021-Nov-22 at 11:55The Uniswap v2 docs for getPair()
function says:
If the pair exists, this function will return its address, else
address(0)
(0x0000000000000000000000000000000000000000
).
And since you're passing a non-existing pair to the getPair()
function, it returns the 0x0
address, and assigns this value to the exchangeAddress
variable.
Then your code is to interact with the 0x0 address, assuming it holds a contract with the UNISWAP_EXCHANGE_ABI
.

...ANSWER
Answered 2021-Jul-08 at 22:06Before I get into the answer, it is very important to use descriptive variable names when writing your code. They might make sense to you, but people like me who aren't you, and possible even you in the future, have a hard time understanding what A, B, M, N, etc mean.
The reason you are getting this error is because your function allPairs()
has a return type of pair[], but you're trying to return long[]. It's a bit hard to understand what you're trying to do because of your variable names, but it seems like when you find a result that you desire you are adding the first and second results separately into an array of longs, which also undermines the point of your pair class. Here's an idea of what it should probably look like instead:
QUESTION
Here is My code:-
class Solution: def allPairs(self, A, B, N, M, X): # Your code goes here
...ANSWER
Answered 2021-Jun-17 at 12:29The error is showing because you are returning only one pair, not all pairs. Also, X - B[j] should be equal to A[j]. So the other element you are returning should be B[j], not A[j].

Answered 2021-Jan-18 at 10:02If you want to achieve adapter based list of chips and more controls than ChipGroup then you can use RecyclerView with chips as an item and to arrange chips in Left-to-Right or Right-to-Left order, you can create a custom LayoutManager.
