Example #1 :

# Ruby code for take_while() method

# declaring array
a = [18, 22, 33, 3, 5, 6]

# declaring array
b = [1, 4, 1, 1, 88, 9]

# declaring array
c = [18, 22, 3, 3, 50, 6]

# take_while
puts "take_while method : #{a.take_while {|num| num > 10 }}\n\n"

# take_while
puts "take_while method : #{b.take_while {|x| x.odd? }}\n\n"

Output :

take_while method : [18, 22, 33]

take_while method : [1]

Example #2 :

# Ruby code for take_while() method

# declaring array
a = [18, 22, 33, 3, 5, 6]

# declaring array
b = [1, 4, 1, 1, 88, 9]

# declaring array
c = [18, 22, 3, 3, 53, 6]

# take_while
puts "take_while method : #{c.take_while {|num| num > 10 }}\n\n"

# take_while
puts "take_while method : #{c.take_while {|num| num.even? }}\n\n"

Output :

take_while method : [18, 22]

take_while method : [18, 22]
