题目地址:
Assume you are an awesome parent and want to give your children some cookies. But, you should give each child at most one cookie. Each child i has a greed factor
Note:
You may assume the greed factor is always positive. You cannot assign more than one cookie to one child.Example 1:
Input: [1,2,3], [1,1]
Output: 1
Explanation: You have 3 children and 2 cookies. The greed factors of 3 children are 1, 2, 3.
And even though you have 2 cookies, since their size is both 1, you could only make the child whose greed factor is 1 content. You need to output 1.
Example 2:
Input: [1,2], [1,2,3]
Output: 2
Explanation: You have 2 children and 3 cookies. The greed factors of 2 children are 1, 2.
You have 3 cookies and their sizes are big enough to gratify all of the children, You need to output 2.
题目比较简单,其实给的示例中已经对我们有提示了,给了两个数组,首先对两个数组进行排序,也就是说对每个孩子的贪婪因子,与蛋糕的大小按从小到大的顺序排序。
首先肯定是看最小的蛋糕能满足谁,然后次小的蛋糕能满足最小贪婪因子后面的哪一位,以此类推:
Java代码实现:
public int findContentChildren(int[] g, int[] s) { ArrayListlg = new ArrayList (); for (int i = 0; i < g.length; i++) { lg.add(g[i]); } ArrayList ls = new ArrayList (); for (int i = 0; i < s.length; i++) { ls.add(s[i]); } Collections.sort(lg); Collections.sort(ls); int content = 0; int k = 0; for (int i = 0; i < ls.size(); i++) { for (int j = k; j < lg.size(); j++) { if (ls.get(i) < lg.get(j)) continue; else { content += 1; k = j + 1; break; } } } return content;}
