벡터에 벡터를 추가하려면 vector insert() 메서드를 사용하면 됩니다.
알고리즘
Begin Declare a function show(). Pass a constructor of a vector as a parameter within show() function. for (auto const& i: input) Print the value of variable i. Declare vect1 of vector type. Initialize values in the vect1. Declare vect2 of vector type. Initialize values in the vect2. Call vect2.insert(vect2.begin(), vect1.begin(), vect1.end()) to append the vect1 into vect2. Print “Resultant vector is:” Call show() function to display the value of vect2. End.

} 출력
Resultant vector is: 1 2 3 4 5
