bisect_right(a, x[, lo[, hi]]) -> index
Return the index where to insert item x in list a, assuming a is sorted.
The return value i is such that all e in a[:i] have e <= x, and all e in a[i:] have e > x. So if x already appears in the list, i points just beyond the rightmost x already there
Optional args lo (default 0) and hi (default len(a)) bound the slice of a to be searched.
