Question

Write Ruby recognizer methods limited? and sorted? that expand the Ruby class Array. The expression array.limited? (amin, amax) should return true if amin lessthanorequalto a[i] lessthanorequalto amax for all values of i. The expression array.sorted? should return 0 if the array is not sorted 1 if a[0] lessthanorequalto a[1] lessthanorequalto a[2] lessthanorequalto... (increasing sequence) -1 if a[0] greaterthanorequalto a[1] greaterthanorequalto a[2] greaterthanorequalto... (decreasing sequence) Show examples of the use of this method.

In Ruby, also please take a screenshot of your output and how to run the code.

Answer 1

Solution class Array #checks amin <-: n and n <-amax for all values in the array #n for number def limited? (amin, amax) self.each do Inl return false unless amin<-n & & n <amax end return true end #this is for checks if given array is sorted in increasing or decreasing sequence. #'n' for number and '1 for index def sorted? self.each_with_index do In, i l break unless n <= self [i+1] if ! != self. length- 1 return "+1" if iself.length 1 end self.each_with_index do In, i l break unless n >= self [i+1] if İ != self. length- 1 return "-1" if iself.length 1 end return 0 end end

#display the output for array is increasing sequence array[1,2, 3,4,5] puts "array: # { array} -array. limited? (0,10) : #{array. limited ? (0,10)}, array. Sorted ?:#{array. Sorted?)" #01 splay the output for array is decreasing sequence array [10,7,5,3,1] puts "array : # { array} -array.limited? (5,11) : #{array. limited ? (5,11)), array. sorted ?:#{array. Sorted?)" #display the output for array is not sorted array [8, 3, 4 ,10, 5] puts "array: # { array)-array.limited? (0,5): #{array. limited ? (0,15)), array. sorted?:# { array. sorted?)" Sample Output: sh-4.3$ ruby main.rb array: [1, 2, 3, 4, 5] array.limited? (0,10) true, array.sorted? +1 array: [10, 7, 5, 3, array.limited?

Copyable Code:

class Array

    #Checks amin <= n and n <= amax for all values in the array

    #n for number

     def limited?(amin,amax)

          self.each do |n|

          end

          return true

     end

#this is for checks if given array is sorted in increasing   or decreasing sequence.

     #'n' for number and 'i for index

     def sorted?

         self.each_with_index do |n, i|

             break unless n <= self[i+1] if i != self.length - 1

             return "+1" if i == self.length - 1
