Как преобразовать массив 2D в 1d в Java
public static int mode(int[][] arr) {
List<Integer> list = new ArrayList<Integer>();
for (int i = 0; i < arr.length; i++) {
// tiny change 1: proper dimensions
for (int j = 0; j < arr[i].length; j++) {
// tiny change 2: actually store the values
list.add(arr[i][j]);
}
}
// now you need to find a mode in the list.
// tiny change 3, if you definitely need an array
int[] vector = new int[list.size()];
for (int i = 0; i < vector.length; i++) {
vector[i] = list.get(i);
}
}
