Given an array
nums
with n
objects colored red, white, or blue, sort them in-place so that objects of the same color are adjacent, with the colors in the order red, white, and blue.We will use the integers
0
, 1
, and 2
to represent the color red, white, and blue, respectively.You must solve this problem without using the library's sort function.
Example 1:
Example 2:
Constraints:
n == nums.length
1 <= n <= 300
nums[i]
is either0
,1
, or2
.
