Write a function smallrange(v) which takes as input a row vector v, and as output returns true if there exists a number c such that all entries in v are contained in the half-open interval [c,c+1), and returns false otherwise. For example, if the input is [2.499, 2, 2.3, 1.5], then the output would be true. If the input is [7, 8], then the output would be false.
