Example #1 :
# Ruby code for map!() 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 ]
# map! puts "map! method : #{a.map! {|num| num > 10 }}\n\n"
# map! puts "map! method : #{b.map! {|x| x.odd? }}\n\n"
|
Output :
map! method : [true, true, true, false, false, false] map! method : [true, false, true, true, false, true]
Example #2 :
# Ruby code for map!() 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 ]
# map! puts "map! method : #{c.map! {|num| num > 10 }}\n\n"
# map! puts "map! method : #{a.map! {|num| num > 10 }}\n\n"
