Expert Solution

Step 1
Vectors in C++
Vectors are sequence containers that have dynamic size. In other words, vectors are dynamic arrays. Just like arrays, vector elements are placed in contiguous storage location so they can be accessed and traversed using iterators. To traverse the vector we need the position of the first and last element in the vector which we can get through begin() and end() or we can use indexing from 0 to size()
