@anubhavb11 iterate till size-1 to display comma and cout the last value directly after that

#3

but i am using for each loop and i dont know how to itrate over inbuilt hashmap using for loop

#4

@anubhavb11
auto start=map.begin();
auto end=map.end();
end–;
for(auto it=start;it<end;it++)
try something like this

#5

there is a problem in it you cant figure out if the end-1 element is going to print or not
