455. Assign Cookies(Solution || Leetcode easy || Java)

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 g[i], which is the minimum size of a cookie that the child will be content with; and each cookie j has a size s[j]. If s[j] >= g[i], 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.

Example 1:

Input: g = [1,2,3], s = [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: g = [1,2], s = [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.

Constraints:

• 1 <= g.length <= 3 * 104
• 0 <= s.length <= 3 * 104
• 1 <= g[i], s[j] <= 231 - 1

SOLUTION:

class Solution {
public int findContentChildren(int[] g, int[] s) {
//first sort both the arrays
Arrays.sort(g);
Arrays.sort(s);

int i = 0;
int j = 0;
int satisfiedChild = 0;

while(i < g.length && j < s.length){
if(g[i] <= s[j]){
i++;
j++;
satisfiedChild++;
}
else{
j++;
}
}

return satisfiedChild;
}
}
