Exercise 5: Vector insertion

Suppose a vector v contains a sequence of integers ordered from lowest to highest. For example, v might contain the values 3, 6, 7, 12. Write a function called insert that takes this vector v as a first argument and an integer k as the second argument. The function inserts k into the vector so that it preserves the order of elements. For example, if v were (3, 6, 7, 12) and k were 5, then after calling the function, v would be (3, 5, 6, 7, 12). In your implementation of insert, do not use the insert function of the vector class (v.insert).
