Title
Body
Let's say I have the following array: arr = [[5, 1], [2, 7]] and I want to find the minimum element, comparing the second element of the elements. The minimum element will be [5, 1] since 1 is less than 7 . I can use the following code: arr.min {|a,b| a[1] <=> b[1]} For calculating the maximum, I can do the same: arr.max {|a,b| a[1] <=> b[1]} That gives [2, 7] . I use the same block all the time. I would like to have that block somewhere and provide it to the min/max function. I hoped something like: blo = lambda {|a,b| a[1] <=> b[1]} arr.min blo would work, but it didn't. Any idea on how I can do this?
