1. 해결방법

그냥 Math.max로 행, 열, 대각선의 합을 구하면 된다.

2. 정답코드

	Scanner sc = new Scanner(System.in);

        int T;
        T = 10;

        for(int test_case = 1; test_case <= T; test_case++)
        {
            int N = sc.nextInt();
            int[][] maps = new int[100][100];

            for (int i = 0; i < 100; i++) {
                for (int j = 0; j < 100; j++) {
                    maps[i][j] = sc.nextInt();
                }
            }
            int maxValue = Integer.MIN_VALUE;

            int leftToRight = 0;
            int rightToLeft = 0;
            for (int i = 0; i < 100; i++) {

                int col = 0;
                for (int j = 0; j < 100; j++) {
                    row += maps[i][j];
                    col += maps[j][i];
                }
                maxValue = Math.max(maxValue, row);
                maxValue = Math.max(maxValue, col);

                leftToRight += maps[i][i];
                rightToLeft += maps[i][100 - i - 1];

            }
            maxValue = Math.max(leftToRight, maxValue);
            maxValue = Math.max(rightToLeft, maxValue);
