Day 7 : Arrays

Problem

Objective

Today, we're learning about the Array data structure.

Task

Given an array,A , of N integers, print A's elements in reverse order as a single line of space-separated numbers.

Input Format

The first line contains an integer, N (the size of our array). The second line contains N space-separated integers describing array A's elements

Constraints

1 <= N <= 1000

1 <= A_i <= 10000 where A_i is the i^th integer in the array

Output Format

Print the elements of array A in reverse order as a single line of space-separated numbers.

Sample Input
4
1 4 3 2

Sample Output
2 3 4 1

Given Code

import math
import os
import random
import re
import sys


if __name__ == '__main__':
    n = int(input())

    arr = list(map(int, input().rstrip().split()))

Solution 1

import math
import os
import random
import re
import sys


if __name__ == '__main__':
    n = int(input())

    arr = list(map(int, input().rstrip().split()))
    print(*reversed(arr))

Solution 2

import math
import os
import random
import re
import sys


if __name__ == '__main__':
    n = int(input())

    arr = list(map(int, input().rstrip().split()))
    print(*arr[::-1])

Solution 3

import math
import os
import random
import re
import sys


if __name__ == '__main__':
    n = int(input())

    arr = list(map(int, input().rstrip().split()))
    rev = list()
    for i in reversed(arr):
        rev.append(i)
    A = " ".join(str(x) for x in rev)
    print(A)
