455. Assign Cookies

Easy

Array Two Pointers Greedy Sorting

Problem Explanation

Explanation

To solve this problem, we can first sort both the greed factor array g and the cookie size array s in ascending order. Then, we can iterate through the arrays and assign cookies to children starting from the child with the lowest greed factor and the smallest cookie size. If the current cookie size is sufficient for the current child, we assign the cookie to the child and move on to the next child and cookie. If the cookie size is not sufficient, we move to the next available cookie. By doing this, we can maximize the number of content children.

Time complexity: O(n log n) - sorting both arrays takes O(n log n) time
Space complexity: O(1) - we are not using any extra space except for a few variables

Solution Code

import java.util.Arrays;

class Solution {
    public int findContentChildren(int[] g, int[] s) {
        Arrays.sort(g);
        Arrays.sort(s);
        
        int i = 0; // pointer for greed factor array
        int j = 0; // pointer for cookie size array
        int contentChildren = 0;
        
        while (i < g.length && j < s.length) {
            if (s[j] >= g[i]) {
                contentChildren++;
                i++;
            }
            j++;
        }
        
        return contentChildren;
    }
}
