455.Assign Cookies

####QUESTION 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 gi, which is the minimum size of a cookie that the child will be content with; and each cookie j has a size sj. If sj >= gi, we can assign the cookie j to the child i, and the child i will be content. Your goal is to maximize the number of your content children and output the maximum number.

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.

####EXPLANATION 其实很简单的,首先将两个数组排序,然后将第一个cookies进行分配,找到满足的之后,进行第二个cookies的分配。
但是这个解法其实有一个问题:如果数组是【2,3】【1,1,1,1】的话,其实输出应该是0,但是还是需要进行mn次的操作。
该解法的时间复杂度是:O(m
n)并不能算是最优的解法。 ####SOLUTION

public int findContentChildren(int[] g, int[] s) {
    int count = 0;
    Arrays.sort(g);
    Arrays.sort(s);
    for(int i = 0 ; i<s.length;i++){
        for(int j = count ;j<g.length;j++){
            if(s[i]>=g[j]){
                count++;
                break;
            }
        }
    }
    return count;
}
