For part a how is this right? Say we have a case of these 4 numbers pushed sequentially, 1, 7, 9, and 11. The k-last behavior will not be correct.

Computer Science Given a dataframe with two columns (x and y), I have found a function on Python that gives a local fit value (essentially between two set values x it gives the average of all values of y). Now the questions asks us to create 2 graphs - one that shows the average per value of x and another one that shows the difference to that average that we found. What does this mean?

Computer science. Correct answer will be upvoted else downvoted.   Think about a n by n chessboard. Its columns are numbered from 1 to n from the top to the base. Its sections are numbered from 1 to n from the passed on to one side. A cell on a convergence of x-th line and y-th section is indicated (x,y). The fundamental corner to corner of the chessboard is cells (x,x) for all 1≤x≤n.    A stage of {1,2,3,… ,n} is composed on the fundamental slanting of the chessboard. There is actually one number composed on every one of the cells. The issue is to segment the cells under and on the principle askew (there are by and large 1+2+… +n such cells) into n associated areas fulfilling the accompanying imperatives:    Each district ought to be associated. That implies that we can move from any cell of a locale to some other cell of a similar area visiting just cells of a similar district and moving from a cell to a neighboring cell.    The x-th area ought to contain cell on the fundamental…
