For these operations we will assume the following:

• key and value are variables of some type.
• We have a std::vectorvec;(value)>
• We have a std::unordered_mapmap;(key),>

1. Add value to the end of vector vec.

vec.push_back(value);

1. Add key with value to map.

1. Add value to current data at index position i in vec.

1. Add value to the current data/value for key in map.

1. Set Boolean variable found to true if key exists in vec.

1. Set Boolean variable found to true if key exists in map. [1-line of code]

1. Set Boolean variable found to true if value exists in map.
