Problem: Pascal’s triangle is a useful recursive definition that tells us the coefficients in the expansion of the polynomial (x + a)^n. Each element in the triangle has a coordinate, given by the row it is on and its position in the row (which you could call its column). Every number in Pasc...

Continuation of this question: I have tried to refactor code according to PEP 8. I tried to raise some errors instead of just print and sys.exit, as was suggested. (should I define much more exceptions for every function and so, or are general ones enough?) Code is not complete, there are a few...

I am working on to find the kth smallest element in min heap. I have got a code for this whose complexity is O(klogk). I tried to improve it to O(k). Below is the code. struct heap{ int *array; int count; int capacity; } intkthsmallestelement(struct heap *h,int i,int ...

I wanted to be sure if the following lines of code are correct. I am trying to plot a 3Dplot of a linear regression with two variables. My linear model ls = lm(mpg ~ disp + qsec, data = mtcars) The minimum and maximum values to predict mmd = min(mtcars$disp):max(mtcars$disp) mmq = min(mt...
