如何从数组中删除一定范围的值? [英] How to delete a range of values from an array?

问题描述

如果array = [1, 2, 3, 4, 5, 6, 7, 8, 9]， 我想从数组中删除一系列元素.

If array = [1, 2, 3, 4, 5, 6, 7, 8, 9], I want to delete a range of elements from array.

例如:我想从该数组中删除索引范围为2..5的所有元素，结果应为[1, 2, 7, 8, 9]

For example: I want to delete all elements with an index in the range 2..5 from that array, the result should be [1, 2, 7, 8, 9]

谢谢.

推荐答案

使用

删除[...]给定范围内的元素.

Deletes the element(s) given by [...] a range.

array = [1, 2, 3, 4, 5, 6, 7, 8, 9]
array.slice!(2..5)
array #=> [1, 2, 7, 8, 9]
