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],

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.

int compare(const void *a,const void *b)
{
    if(*(int *)a > *(int *)b)
        return 1;
    else if(*(int *)a < *(int *)b)
        return -1;
    else 
        return 0;
}

int findContentChildren(int* g, int gSize, int* s, int sSize)
{
    /*从小到大排序g和s*/
    qsort(g,gSize,sizeof(int),compare);
    qsort(s,sSize,sizeof(int),compare);
    int pointG = 0;
    int pointS = 0;
    
    while((pointG < gSize) &&(pointS < sSize))
    {
        if(g[pointG] <= s[pointS])
        {
            pointG++;
            pointS++;
        }
        else
            pointS++;
        
    }
    
    return pointG;
    
}
