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;
}
```
