`list-sorted?``<``lis`procedure`vector-sorted?``<``v``#!optional``start``end`procedureThese procedures return true iff their input list or vector is in sorted order, as determined by

*<*. Specifically, they return`#f`iff there is an adjacent pair …*X Y*… in the input list or vector such that*Y*<*X*in the sense of*<*. The optional*start*and*end*range arguments restrict`vector-sorted?`to examining the indicated subvector.These procedures are equivalent to the SRFI 95

`sorted?`procedure when applied to lists or vectors respectively, except that they do not accept a key procedure.
