我正在尝试计算顺序确实很重要的两个数组之间的差异。例如:
array_one = ["A", "B", "C"]
array_two = ["B", "C", "A"]
这会产生 3 个差异，因为:
array_one[0] != array_two[0]
array_one[1] != array_two[1]
array_one[2] != array_two[2]
另一个例子:
array_one = ["Z", "X", "Y"]
array_two = ["Z", "W", "Y"]
这会产生 1，因为:
array_one[0] == array_two[0]
array_one[1] != array_two[1]
array_one[2] == array_two[2]
非常感谢任何建议。
最佳答案
这个怎么样
array_one = ["A", "B", "C"]
array_two = ["A", "C", "A"]
array_one.select.each_with_index { |item, index|
array_two[index] != item
} => #B and C
