QUESTION
I want to know some of the reasons that can cause below exception. I am unable to find this message Cannot find message
in jsch-0.1.54.jar
. There exists some straight forward messages like file not found
and others that make sense. But I need more information about this one so that I can reach to the root cause.
ANSWER
Answered 2020-Jun-22 at 08:05The error message comes from your server. It's indeed quite strange message, but I assume that it's some custom SFTP server that deals with some "messages" rather than plain files.
So the message basically translates to "Cannot find file" error of a traditional SFTP server. Even the error code 2 (SSH_FX_NO_SUCH_FILE
) supports that.
Your path in remoteFile
is probably wrong.

"There's a robot in the top left corner of the grid. The robot can only move right, or down. The grid can contain invalid/blocked cells that the robot cannot step onto. Verify if there is a path to the bottom right cell in the grid from the top left."
The SolutionsI have two solutions, both of which use memoization in order to prevent re-doing the same work that you might do in a naive implementation.
Solution 1:
...ANSWER
Answered 2019-Jun-15 at 00:19The correct way to figure this out is to run it under a profiler (though I don’t know if there is good Python profiler).
But here are some things I guess are probably less efficient in solution 1:
In solution 1, you first check whether you’ve reached the bottom-right cell, and if so, you return early. If you haven’t reached the bottom-right cell, you then check the cache and possibly skip some work. Since most cells are not the bottom-right cell, the bottom-right test usually does not cause an early return.
In solution 2, you first check the cache and possibly return early. If the cache check fails, then you check whether you’ve reached the bottom-right cell. So if the cache check hits often, you skip a lot of bottom-right checks that you perform in solution 1.
In solution 1, you fetch
cache[currentRow][currentColumn]
on line 9 and on line 14. In solution 2, you only fetch it on line 6. So solution 1 performs on the order of twice as many of these fetches as solution 2.

True.
The fastest implementation would be coded in assembler with the use of the registers:
