Given an array 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.
Here, we will use the integers 0, 1, and 2 to represent the color red, white, and blue respectively.
Note: You are not suppose to use the library‘s sort function for this problem.
Example:
Input: [2,0,2,1,1,0] Output: [0,0,1,1,2,2]
Follow up:
class Solution {
public:
void sortColors(vector<int>& nums) {
int len = nums.size();
for (int i = 1; i <= len; ++i) {
for (int j = i-1; j > 0; --j) {
if (nums[j] < nums[j-1]) {
int con = nums[j];
nums[j] = nums[j-1];
nums[j-1] = con;
}
}
}
}
};
