1. IfProgramIf random element access is required, the vector or deque container should be used.

2. If the program must insert or delete elements in the middle of the container, the list container should be used.

3. If the program is not in the middle of the container, but inserts or deletes elements in the header or tail of the container, deque container should be used.
