How can I delete one element from an array by value
Solution 1:
I think I've figured it out:
a = [3, 2, 4, 6, 3, 8]
a.delete(3)
#=> 3
a
#=> [2, 4, 6, 8]
Solution 2:
Borrowing from Travis in the comments, this is a better answer:
I personally like
[1, 2, 7, 4, 5] - [7]which results in=> [1, 2, 4, 5]fromirb
I modified his answer seeing that 3 was the third element in his example array. This could lead to some confusion for those who don't realize that 3 is in position 2 in the array.
