How do you split a vector in C++?

Slicing a Vector in C++

  1. Pre-requisite: Vectors in C++
  2. Method 1: The idea is to copy the elements from this range X to Y to a new vector and return it.
  3. Method 2: The above approach can be implemented using Range Constructor.
  4. Method 3: We can also use inbuilt function slice() in C++ STL to slice the given vector.
