Task 2: Ascending Numbers

Submitted by: [49]Mohammad Sajid Anwar
     __________________________________________________________________

   You are given a string, $str, is a list of tokens separated by a single
   space. Every token is either a positive number consisting of digits 0-9
   with no leading zeros, or a word consisting of lowercase English
   letters.

   Write a script to check if all the numbers in the given string are
   strictly increasing from left to right.

Example 1

Input: $str = "The cat has 3 kittens 7 toys 10 beds"
Output: true

Numbers 3, 7, 10 - strictly increasing.

Example 2

Input: $str = 'Alice bought 5 apples 2 oranges 9 bananas'
Output: false

Example 3

Input: $str = 'I ran 1 mile 2 days 3 weeks 4 months'
Output: true

Example 4

Input: $str = 'Bob has 10 cars 10 bikes'
Output: false

Example 5

Input: $str = 'Zero is 0 one is 1 two is 2'
Output: true
