vue中 把一段长数组按照指定份数 均分 sliceArray(array, size) { var result = []; for (var x = 0; x < Math.ceil(array.length / size); x++) { var start = x * size; var end = start + size; result.push(array.slice(start, end)); } return result; },
Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: Each element in the result must be unique. The result can be in any order. 这道题让我们找两个数组相同的部分,难度不算大,我们可以用个set把nums1都
Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2, 2]. Note: Each element in the result should appear as many times as it shows in both arrays. The result can be in any ord
