Problem

Solution

Initial thoughts

Python implementation

class :
    def findContentChildren(self, g, s):
        """
        :type g: List[int]
        :type s: List[int]
        :rtype: int
        """
        g.sort()
        s.sort()
        g_len = len(g) - 1
        c = 0
        for s_i in s:
            if c > g_len:
                break
            if s_i >= g[c]:
                c += 1
        return c

Java implementation

class  {
    public int findContentChildren(int[] g, int[] s) {
        Arrays.sort(g);
        Arrays.sort(s);
        int g_len = g.length - 1;
        int c = 0;
        for(int s_i : s){
            if(c > g_len){ break; }
            if(s_i >= g[c]){ c++; }
        }
        return c;
    }
}

Time complexity

O(nlogn).

Space complexity

O(1).
