2차원 배열에서 오름차순 정렬을 하려고 하는데 
일차원 배열에서는 이렇게 했는데
if(Num1[numi] > Num1[numj]){
                                compare = Num1[numi];
                                Num1[numi] = Num1[numj];
                                Num1[numj] = compare;
이차원 배열에서는 어떻게 해야하죠,.>?
예를들어 1행1열, 2행2열, 3행3열 을 오름차순으로 하려고 하면요,.,..
