Description | Removes the element at the specified position in this vector. Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the vector.
Syntax |
    remove(index)
Parameters |

index | int: the index to remove the element

Returns | The element removed
Usage | Application
