一、数组与矩阵

1、把数组中的 0 移到末尾

283. Move Zeroes (Easy)

Leetcode / 力扣

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

public void moveZeroes(int[] nums) { int idx = 0; for (int num : nums) { if (num != 0) { nums[idx++] = num; } } while (idx < nums.length) { nums[idx++] = 0; } }

2、改变矩阵维度
