# Task 2: Ascending Numbers
# Submitted by: 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
