/*
for taking in white-spaces, getline(std::cin>>std::ws,s);
if even, sub1=s.substr(0,s.length()/2); sub2=s.substr(s.length()/2,s.length()-1);
if odd, sub1=s.substr(0,s.length()/2); sub2=s.substr(s.length()/2+1,s.length()-1);
check complexity every time
for having sorted inputs, use multiset and use set for unique keys.
for ordered sequence of unique keys use map, and for unordered sequence of unique keys use unordered_map.
for multiple elements having same keys use multimap.
array dynamically resize korar jonno vector.
top element theke reverse sorted inputs er jonno priority_queue.
Raw string declaration string R("Hello\tWorld\n");
For having the ability to merge two sorted data-structures, use list.
For inputs in both head and tail use Deque.
Basics- LIFO Stack and FIFO Queue.
Don't forget Tuple!
