Scope: Many programming languages implement scope for variables – and they are context sensitive. For example a global scope variable will be over-ridden using local variable definition. You need to implement simple interpreter which tells us current value of a variable, if its not defined then value should be zero, Input will start with ‘[‘ and…
puts "Enter your statements separated by a carriage return, The matching braces will terminate the loop"
variables = Hash.new(Hash.new)
opening_brackets = 0
closing_brackets = 0
while true
variable = nil
level = nil
value = nil
input = gets.chomp

A simple program to sort a list of number ranging 1-130 in ascending order
require 'benchmark'
def smarter_way(unsorted_array, size, sorted_array)
maggic_array = Array.new(130) {|i| i = ({ i => 0 }) }
unsorted_array.each do |num|
maggic_array.each do |hash|
if hash.keys.first == num
hash[num] = hash[num] + 1
end
end
