题目：68. 文本左右对齐 - 力扣（LeetCode）

没啥难的，就是麻烦点。

class Solution {
public:vector<string> fullJustify(vector<string>& words, int maxWidth) {vector<string> ret;vector<string> temp;int w = 0;int total = 0;int spaces;int a, b;string line;for (int i = 0; i < words.size(); i++) {if (w + words[i].length() > maxWidth) {spaces = maxWidth - total;line = "";if (temp.size() == 1) {line = temp[0];for (int j = 0; j < spaces; j++) {line += " ";}} else {a = spaces / (temp.size() - 1);b = spaces % (temp.size() - 1);for (int j = 0; j < temp.size(); j++) {line += temp[j];if (j == temp.size() - 1) {break;}for (int k = 0; k < a; k++) {line += " ";}if (b > 0) {line += " ";--b;}}}ret.push_back(line);temp.clear();w = 0;total = 0;}temp.push_back(words[i]);w += words[i].length() + 1;total += words[i].length();}line = "";for (int i = 0; i < temp.size(); i++) {if (i) {line += " ";}line += temp[i];}while (line.size() < maxWidth) {line += " ";}ret.push_back(line);return ret;}
};
