TheLordIsGr8:
Is this a kind of competition or something?

I have a one-liner. But I spread it on two lines for ease of understanding for some beginners who may be here.
Also I posted another solution which is not a solution to the problem at all, but for reversing a string, which could be viewed as a subset of a list.

Ok. here is my final solution in one line using python

Given a list, x, the list could be reversed in one line like so

x = [x[len(x)-1-i] for i in range(len(x))]

print(x)

TheLordIsGr8:
# Using a recursive algorithm in 4 lines to reverse a string

1. def reverse_string(a_str):
2.     if a_str == '':
3.         return a_str
4.     return a_str[-1] + reverse_string(a_str[:-1])
5. print(reverse_string('nairaland'))

TheLordIsGr8:
# Using python 3 list comprehensions
# you can just copy this post as is into jupyter notebook or any IDE and run it to verify

from random import randint # import random integer generator

ints = [randint(x, 10*x) for x in range(10)] # create a random list of integers

# Two lines for better understanding

k = len(ints)
rev_ints = [ints[k-1-i] for i in range(k)]
print(rev_ints)




# here the same code is as a one-liner. just substitute the value of k directly in the list comprehension

rev_ints = [ints[len(ints)-1-i] for i in range(len(ints))]



# Here it is using a list of strings

animals = ['goat', 'dog', 'cat', 'mouse']
rev_animals = [animals[len(animals)-1-i] for i in range(len(animals))]
print(rev_animals)

# If you need to change the original list all you need to do is to reassign the original list to the value of the reversed list like so

ints = rev_ints
animals = rev_animals

Php

$preserved = array_reverse($input, true);

FrankLampard:
In Java

Collections.reverse(list);

TheLordIsGr8:
Is the list you will provide already sorted?

Will there be need to sort the list if it is not already sorted?

In python it's as easy as calling

input_list = sorted(input_list, reverse=False/True)

But it only W3schools I knew, can u help me with any other site dat could actually help sir, more also, I have laptop; any tutorial or apps I need to download in order to learn by it.

Another question, wat best suitable to learn programming; Andriod, Bb, Window or even Java phones coz I so much enjoyed using Java phones back den in learning HTML coz all is d button is wat I learnt by heart!!!
