I have 2 code submissions on codeforces -
https://codeforces.com/contest/762/submission/29695191
& https://codeforces.com/contest/762/submission/29695201
both have the exact same code except for the usage of $ vs. () . One with the $ exceeded the time limit on the 6th test and the other passed all the tests.
Any suggestions on why that might be the case?
They're exactly the same. There's just some variance in runtime - your passing test case is within 5% of failing on time as well.

I want to input a large number by scientific notation, for example of distance to sun.
distance = float(input("distance to sun?:"))
I tried to enter 1.471*10**11 and 1.471e11, but both said "could not convert string to float"
Do I have to type the multiple "0"? Thanks for answering in advance.

I am new to machine learning. I am trying to learn feature selection from this link. Here they have a line of code which is given below
search = GridSearchCV(pipeline, grid, scoring='neg_mean_squared_error', n_jobs=-1, cv=cv)
But whenever I try to run this code I get the error
I cannot find where to import neg_mean_squared_error from. I am not sure where I should write the function myself or not. The tutorial isn't clear on this issue.
It is just a typo.
You need
neg_mean_absolute_error
You typed
neg_mean_absolure_error
using an r instead of t

I am struggling with an excel formula with multiple IF AND conditions. maybe you can help me. Here is an explanation of what I want to achieve:
List different prices if TWO conditions are met.
If A1=Ferrari AND B1=red, price=500; IF A1=Ferrari AND B1=gold, price=550; IF A1=Toyota AND B1=red, price=100, IF A1=Toyota and color=gold, price=110, else leave cell blank´
I hope you understand what I want to achieve and can help me.
This is what I tried but it gives me an error. I am using google sheets by the way.
=IF(AND(I27="ferrari"; K27="red")Variables!$R$1;IF(AND(I27="ferrari"; K27="gold")Variables!$R$2;IF(AND(I27="toyota"; K27="red")Variables!$V$3;IF(AND(I27="toyota"; K27="gold")Variables!$V$4;""))))
I think you've got your semi colons and commas mixed up! Try this...
=IF(AND(I27="ferrari",K27="red"),Variables!$R$1,IF(AND(I27="ferrari",K27="gold"),Variables!$R$2,IF(AND(I27="toyota",K27="red"),Variables!$V$3,IF(AND(I27="toyota",K27="gold"),Variables!$V$4,""))))
You were also missing commas after some of your closing parentheses.

I recently created my first Azure Function, which runs fine - I've had ~16,000 requests in the last hour which I can see under the monitor tab. However the pulse telemetry screen shows nothing - just empty graphs as if no functions are being run. I've done the whole opening new tabs, different browsers, reboot thing and no change.
Any ideas?

When I type > file.extension I know that the file is replaced by a empty file.
What if then I type > / ? My / partition will be erased and I'll lost everything in it?
I'm curious and wondering if someone already tried this.
