Solve tasks

There is hard limited set numbers is allowed. But in the input can be any number. We need to select the closest number from allowed set to use next.

This class can help to solve this task.

By default script selects low close number:

use AndyDune\SelectClosestNumberFromSet;
$object = new SelectClosestNumberFromSet([0, 20, 40]);
$next = $object->select(-5); // = 0
$next = $object->select(5); // = 0
$next = $object->select(39); // = 20
$next = $object->select(100); // = 40

Use method selectHigh to select high allowed number:

use AndyDune\SelectClosestNumberFromSet;
$object = new SelectClosestNumberFromSet([0, 20, 40]);
$object->selectHigh();
$next = $object->select(-5); // = 0
$next = $object->select(5); // = 20
$next = $object->select(39); // = 40
$next = $object->select(100); // = 40
