=====Problem Statement=====
You are asked to ensure that the first and last names of people begin with a capital letter in their passports. For example, alison heck should be capitalised correctly as Alison Heck. 

alison heck => Alison Heck

Given a full name, your task is to capitalize the name appropriately.

=====Input Format=====
A single line of input containing the full name, S.

=====Constraints=====
0<len(S)<1000
The string consists of alphanumeric characters and spaces.

Note: in a word only the first character is capitalized. Example 12abc when capitalized remains 12abc.

=====Output Format=====
Print the capitalized string, S.

Difficulty: introductory

Starter code:

#!/bin/python3

import math
import os
import random
import re
import sys

# Complete the solve function below.
def solve(s):

if __name__ == '__main__':
    fptr = open(os.environ['OUTPUT_PATH'], 'w')

    s = input()

    result = solve(s)

    fptr.write(result + '\n')

    fptr.close()


Solutions:
s = input()
s_ar = s.split(' ')
final_ar = []
space = ' '
for w in s_ar:
    final_ar.append(w.capitalize())
print((space.join(final_ar)))
