Problem:
Spreadsheet

Your task is to perform a simple table calculation.

Write a program which reads the number of rows r, columns c and a table of r × c elements, and prints a new table, which includes the total sum for each row and column.

Input

In the first line, two integers r and c are given. Next, the table is given by r lines, each of which consists of c integers separated by space characters.

Output

Print the new table of (r+1) × (c+1) elements. Put a single space character between adjacent elements. For each row, print the sum of it's elements in the last column. For each column, print the sum of it's elements in the last row. Print the total sum of the elements at the bottom right corner of the table.

Constraints

1 ≤ r, c ≤ 100

0 ≤ an element of the table ≤ 100

Sample Input

4 5
1 1 3 4 5
2 2 2 4 5
3 3 0 1 1
2 3 4 4 6

Sample Output

1 1 3 4 5 14
2 2 2 4 5 15
3 3 0 1 1 8
2 3 4 4 6 19
8 9 9 13 17 56

Solution in Scala (judge verdict: Accepted)

import scala.io.Source

object Main extends App {
  val lines = Source.stdin.getLines.map(_.split(" ").map(_.toInt).toList).toList
  val (rows, cols) = (lines(0)(0), lines(0)(1)+1)
  val linesOfNum: List[List[Int]] = lines.tail

  def appendSum(xs: List[Int]): List[Int] = {
    val newLine =  xs :+ xs.sum
    println(newLine.mkString(" "))
    newLine
  }


  def addEachElement(acc: List[Int], ixx: List[List[Int]]): List[Int] = ixx match {
    case Nil => acc
    case h :: tail => addEachElement((acc zip appendSum(h)).map { case (i, j) => i + j }, tail)
  }

  println(addEachElement(List.fill(cols)(0), linesOfNum).mkString(" "))
}
