Concept explainers

Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.

Question

Nearest smaller element
def nearest_smaller(items):
Given a list of integer itema, create and return a new list of the same length but where each
element has been replaced with the nearest element in the original list whose value is smaller. If no
smaller elements exist because that element is the minimum of the original list, the element in the
result list should remain as that same minimum element.
If there exist smaller elements equidistant in both directions, you must resolve this by using the
smaller of these two elements. This again makes the expected results unique for every possible
value of items, which is necessary for the automated testing framework to work at all. Being
permissive in what yvou accept while being restrictive in what you emit is a pretty good principle to
follow in all walks of life, not just in programming.

The input begins with an integer indicating the number of integers that follow.
