    Description

    I'm just playing with kumite !!!!!

     Code 
    def is_odd(input)
  input & 1 == 1
end
    Test Cases 
    Test.describe "Fixed tests" do
  Test.it "should pass fixed tests" do
   Test.assert_equals(is_odd(1), true)
   Test.assert_equals(is_odd(2), false)
   Test.assert_equals(is_odd(13), true)
   Test.assert_equals(is_odd(18284), false)
   Test.assert_equals(is_odd(-1), true)
  end
end
        
Test.describe "Random Tests" do
  Test.it "should pass random tests" do

    100.times do
      n = rand(-(10**rand(1..5))..10 ** rand(1..5))
      Test.assert_equals(is_odd(n), n & 1 == 1)
    end
  end
