Bucket sort in c++

#1

in the code:
v[m].pushback(s[i]);
what if two students have same marks ?
will it overwrite the content in that particular index?

#2

@Tiwary725 push_back appends in the vector, it does not overwrite anything

#3

What I meant to say is that if two students have same marks lets say 78, then at the index 78 of the vector, marks of both students will be stored??

Is it possible to push two objects in a particular index of the vector??

@Tiwary725 a vector of int type can hold only 1 element. But if the vector type is also vector then more than 1 objects can be stored at the same index (like a 2d array)
