Drop the last n elements of a finite sequence, and return the rest.Given a finite Sequencexs with a linearization of [x1, ..., xm] and a non-negative IntegralConstantn, drop_back(xs, n) is a sequence with the same tag as xs whose linearization is [x1, ..., xm-n]. If n is not given, it defaults to an IntegralConstant with a value equal to 1. More...
