Problem 1118. Colon operator of two vectors

You are given two vectors of equal length: VecStart, VecEnd

Each vector contain a set of integers, where VecEnd(j)>=VecStart(j)

You have to return a set (vector) of integers of the following form:

Output =... [ VecStart(1):VecEnd(1), VecStart(2):VecEnd(2),..,VecStart(end):VecEnd(end)]

For example:

VecStart = [1 10 4]

VecEnd = [3 10 7]

--> Output = [1 2 3 10 4 5 6 7]
