Code #1 : Example for compact() method
# Ruby code for compact() method# showing how to remove nil values # declaring arraya = [18, 22, 33, nil, 5, 6] # declaring arrayb = [5, 4, nil, 1, 88, 9] # declaring arrayc = [18, 22, nil, 40, 50, 6] # removing nil value from arrayputs "removing nil value : #{a.compact}\n\n" # removing nil value from arrayputs "removing nil value : #{b.compact}\n\n" # removing nil value from arrayputs "removing nil value : #{c.compact}\n\n" |
Output :
removing nil value : [18, 22, 33, 5, 6] removing nil value : [5, 4, 1, 88, 9] removing nil value : [18, 22, 40, 50, 6]
Code #2 : Example for compact() method
# Ruby code for compact() method# showing how to remove nil values # declaring arraya = ["abc", "nil", "dog"] # declaring arrayb = ["cow", nil, "dog"] # declaring arrayc = ["cat", nil, nil] # removing nil value from arrayputs "removing nil value : #{a.compact}\n\n" # removing nil value from arrayputs "removing nil value : #{b.compact}\n\n" # removing nil value from arrayputs "removing nil value : #{c.compact}\n\n" |
Output :
removing nil value : ["abc", "nil", "dog"] removing nil value : ["cow", "dog"] removing nil value : ["cat"]
