Oh genes..

It's okay

Is there any rule for the sequence?

Can it be in the form of:
AAAAA T ACGT
AAAA T AACGT
AAA T AAACGT
AA T AAAACGT
A T AAAAACGT
T AAAAAACGT
and so on?

Hi, I am using hiredis as redis c client.But it bot not thread-safe.I have tried to use a redisContext per thread but it seems not work.eredis supports thread safety, but few people seem to use it

What was the time complexity of your approach? Everything I can think of is insanely inefficient... So, it's interesting...

please format your code

Can someone please assist me hear
Why does getline function only display the second name not the first while typing in the input ?

Thanks for the correction 😊

there you go, buddy

Why does getline function only display the second name not the first while typing in the input ?
you're reading the first name before the getline
vinícius*
you're doing cin >> name and then the getline
vinícius*
therefore overwriting the first name with the second

disclaimer: i started programming in april ! a newbie here as well!
hello! i searched high and low on stack overflow but i don’t seem to find my answer...
so all i want to do is printf ALL my scanf using array!
in the first pic is a code that is done with integer.
i tried to implement what i have with it to apply it into char but it does not print out the correct things.
the second pic is the problem i’m currently encountering.

Could you give an example of how you'd want it to work, and what it's currently doing?
Like the terminal output/input

Guys i have a problem with fifo files. So its in a while loop in the two programs. The first loop works fine. But the second one, the programs who asks a fgets simply do enter without ever asking.
Cengizhan
Generation should be linear, right? Comparison 10^5 strings to 10^5 strings, I do not think so.

bruh

Thats why you need to describe your expectation about in terms of "strings", "chars" etc. on linear or quadratic way.

Hi here, need some help please.
Here is a segment of code, i want it to run while waiting for user to press a key but it loops just once and stops. Any idea on what i should do? please (I want it to keep printing '1' till the key is entered.
#include <ncurses.h>
int main (void){
char press;
while(press != 'q'){
printf("1");
press = getch();
}
printf("You pressed 'q'");
}
Thank you
Sorry for the late reply friend
while( getchar() != 'q')
printf("q\b") ;
printf("\nq") ;
Noble Friend

printf("q\b") ;
printf("\nq") ;
yeah, but this keeps waiting for a key to be pressed after every execution. that's why i needed the help.
(for example, car should keep moving until the driver says stop. so if the driver says 'go' or says nothing, the car should keep moving.)
So the issue is the tire turns just once and wait for driver instead of continuous turning.
/*Abstract example but explains better. */

Hi, how can i make, 2 program comunicating witch each other with 2 named pipe. The program dosnt end but comunicate constantly. (after the first round in the while loop i cant make it work)
particaney 🐸🍲
One program says a number. The other gives a answer and waits back the number from the first program. And this non stop. With 2 distinct fifo file

Oh no ... It just prints the last event the user types in. I have actually encountered this previously. 🥺

Reading 10^5 strings with 10^5 characters is 10^10 read operations(when we think in terms of no. of times we read each character).
So just reading the input that you described is quadratic. Isn't it?
BTW, What's the memory limit to your question?
Ajay
I initially thought of a Trie data-structure that holds each string. So, after inserting all the strings, when we try to generate a given string, then we just check if the none of the strings that have already been inserted have their i_th character to be either of A, T, C, G. If not, then you know that you can choose this i_th character to be this non-occurring character then the rest of the characters can be any thing. For simplicity, I will choose all of these characters be A.
But, still going through all these strings and that too character wise isn't a good approach. What do you think?
Ajay
BTW, you didn't tell the time-limit.
Ajay
N here is # of strings or multiplication of length and their count?
Ajay
Ofc, O(something) doesn't give you the exact space that your algorithm use and I don't think the interviewer will have any problem if the data-structure that you use takes an equivalent amount of space that the input itself takes.
yes, the time limit is a concern here.
Ajay
Interested to know your approach?
Cengizhan
Create 10^5 hash values for 10^5 strings. And generate new one and compare generated string hash value with existing one. But still it is quadratic.

Or holding strings as a key map and new generating string would not be inserted into map, it has been already known one.

You can set up a function that returns the "negative" of a given genome

Like, say A is the negative of G (arbitrarily), and something similar for all the rest

because the given set is guaranteed to have no clones, right ?

Are the string fixed-length?
