TallPeople - TopCoder


https://community.topcoder.com/stat?c=problem_statement&pm=2923&rd=5854
    A group of people stand before you arranged in rows and columns. Looking from above, they form an R by C rectangle of people. You will be given a String[] people containing the height of each person. Elements of people correspond to rows in the rectangle. Each element contains a space-delimited list of integers representing the heights of the people in that row. Your job is to return 2 specific heights in a int[]. The first is computed by finding the shortest person in each row, and then finding the tallest person among them (the "tallest-of-the-shortest"). The second is computed by finding the tallest person in each column, and then finding the shortest person among them (the "shortest-of-the-tallest").

    public int[] getPeople(String[] people) {
        int min = Integer.MAX_VALUE;
        int max = Integer.MIN_VALUE;
        int len1 = people.length;
        if (len1 == 0return null;
        String[] hgts = people[0].split(" ");
        int len2 = hgts.length;
        if (len2 == 0return null;
        int mx[][] = new int[len1][len2];
 
        for (int i = 0; i < len1; i++) {
            String line = people[i];
            String[] heights = line.split(" ");
            int _min = Integer.MAX_VALUE;
            for (int j = 0; j < len2; j++) {
                int tmp = Integer.parseInt(heights[j]);
                mx[i][j] = tmp;
                if (tmp < _min) _min = tmp;
            }
            if (_min > max) max = _min;
        }
        for (int j = 0; j < len2; j++) {
            int _max = Integer.MIN_VALUE;
            for (int i = 0; i < len1; i++) {
                if (mx[i][j] > _max) _max = mx[i][j];
            }
            if (_max < min) min = _max;
        }
 
        return new int[] {max, min};
