Code #1 : Example for bsearch() method

# Ruby code for bsearch() method

# declaring array

# declaring array
b = [111.11, 2.5, 4.3, 2.224]

# array elements that meets the condition
puts "search : #{a.bsearch {|x| x >=4 }}\n\n"

puts "search : #{b.bsearch {|x| x >=3 }}\n\n"

puts "search : #{a.bsearch {|x| x >=2 }}\n\n"

puts "search : #{b.bsearch {|x| x >=2 }}\n\n"

Output :

search : 4

search : 4.3

search : 2

search : 111.11
