我已经开始了:
def split_array(array,size)
index = 0
results = []
if size > 0
while index <= array.size
res = array[index,size]
results << res if res.size != 0
index += size
end
end
return results
end

如果我上运行它,[1,2,3,4,5,6]喜欢split_array([1,2,3,4,5,6],3)它会产生此阵:
[[1,2,3],[4,5,6]].在Ruby 1.8.7中是否有可以做到这一点的东西?
sep*_*p2k 10
[1,2,3,4,5,6].each_slice(3).to_a
#=> [[1, 2, 3], [4, 5, 6]]

对于1.8.6:
require 'enumerator'
[1,2,3,4,5,6].enum_for(:each_slice, 3).to_a
