Problema
Ver traducciónRotate the list to the right by steps positions: the last element moves to the front, steps times.
Implement rotate_right(numbers, steps).
Input
numbers: The list of integers. steps: How many positions to rotate.
Output
Return the rotated list.
Restricciones
0 ≤ length ≤ 100,000; 0 ≤ steps ≤ 10⁹
Ejemplos
Ejemplo 1
Entrada:
steps = 2
numbers = [1, 2, 3, 4, 5]
Salida esperada:
expected = [4, 5, 1, 2, 3]Entrada:
long long steps = 2;
std::vector<long long> numbers = {1, 2, 3, 4, 5};
Salida esperada:
std::vector<long long> expected = {4, 5, 1, 2, 3};Entrada:
long steps = 2;
long[] numbers = new long[] {1, 2, 3, 4, 5};
Salida esperada:
long[] expected = new long[] {4, 5, 1, 2, 3};Explicación
Two right rotations: [5, 1, 2, 3, 4], then [4, 5, 1, 2, 3].
Ejemplo 2
Entrada:
steps = 3
numbers = [1, 2, 3]
Salida esperada:
expected = [1, 2, 3]Entrada:
long long steps = 3;
std::vector<long long> numbers = {1, 2, 3};
Salida esperada:
std::vector<long long> expected = {1, 2, 3};Entrada:
long steps = 3;
long[] numbers = new long[] {1, 2, 3};
Salida esperada:
long[] expected = new long[] {1, 2, 3};Explicación
Rotating by the length brings the list back: [1, 2, 3].
