It is not repetition. It is called function overloading. Basically if you have a function/method and you have two different data structure types as input you have to repeat the method name for different implementations of that method and C++ will automatically use the correct implementation.

It is certainly not good practice and Templates should be used in Modern C++. But it isn't repetition.
