[SOLVED] CSE110 Lab 8

Lab 7

Rules:

•   You are not allowed to use any array or String
•   One only line where the word “String” may appear is in public static void main(String [] args) {
•   The word “char” must not be anywhere in your solutionOverall hint: Imagine all outputs as a matrix of space and star. Then count spaces and stars to find out the trend of increment or decrement of number of stars/spaces. Utilize several to control when ‘star’ will be printed, when ‘space’ will be printed and when ‘ will be printed.

  PROBLEM 1) Number Line Sample input:
  6
  Sample output

  123456

  PROBLEM 2) Star Line
  Print as many stars as given in input Sample input:
  6
  Sample output
  ******

  PROBLEM 3) Rectangle Sample input:
  4
  6

  Sample output

  ******
  ******
  ******
  ******
  

  Hint: 4 and 6 means 4 lines of stars having 6 stars in each line.

  PROBLEM 4) Rectangle Sample input:
  4
  6

  Sample output

  123456
  123456
  123456
  123456
  

  Hint: 4 and 6 means 4 lines of numbers having 1..6 in each line.
