Refactor vector initialization and output display

[Silicon27]

Refactored code to initialize vector from map directly and improved output formatting.

Fixes issue:
Formatting issues and initialization shortcuts.

Changes:

for(auto i : mp1)   //inserting map values into vector
{
    vec1.push_back(make_pair(i.first,i.second));
}

was unnecessary, as you could initialize the vector and give it all the values of the map by

vector<pair<string,int>> vec1(mp1.begin(), mp1.end());
