Parkside's Other Triangle is generated from two positive integers, one for the size and one for the seed. For example,

  Size 4, Seed 3
  3 4 6 9
    5 7 1
      8 2
        3



Size gives the number of columns. Seed specifies the starting value for column 1. Column_i contains i values. The first number is the seed. Then each succesive number is produced by adding one. The numbering continues in every column. When numbering reaches to 9, the value continues from 1. When numbering in a column reaches to end, it continues from the next column.

Question: Write a program that reads a pair of positive integers and produces Parkside's Other Triangle.

Input specification
You will be given two integer numbers, number of columns and the seed (numCols and seed) where 1 ≤ numCols ≤ 20 and 1 ≤ seed ≤ 9.

Output specification
Show the given Parkside's other triangle. Each number is followed by a space and every row_i contains (i-1)*2 spaces.
