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…

Correct answer will be upvoted else Multiple Downvoted. Computer science. Athenaeus has recently wrapped up making his most recent melodic piece and will introduce it tomorrow to individuals of Athens. Tragically, the tune is somewhat dull and almost certain will not be met with a warm gathering. His tune comprises of n notes, which we will treat as certain integers. The variety of a tune is the number of various notes it contains. As a supporter of music, Euterpe looks after arrangers and guides them all through the method involved with making new tunes. She chose to help Athenaeus by changing his melody to make it more assorted. Being a minor goddess, she can't self-assertively change the tune. All things being equal, for every one of the n notes in the tune, she can either leave it for what it's worth or increment it by 1. Given the tune as an arrangement of integers portraying the notes, discover the maximal, attainable variety. Input The input comprises of numerous…
