Multiples of vectors given a real number c, we can multiply a vector by c by multiplying its magnitude by c. Classify the elements of the vector by putting those smaller than x in the left part of the vector, those larger than y in the right part and those inside the interval in the middle. Vectors can also be interpreted geometrically in the 3dimensional space xyz. Vectors are sequence container that can change size. We have a vector of elements v and an interval x,y x.
