Algorithm

  • STEP 1: START
  • STEP 2: SET lines=10
    SET i=1
  • STEP 3: REPEAT STEP 4 to 15 UNTIL i is less than or equals to lines
  • STEP 4: SET count =0
    SET j=1
  • STEP 5: REPEAT STEP 6 and 7 UNTIL j is less than lines
  • STEP 6: IF count is less than (i-1)
    IF j is not less than (lines-i+1)
    PRINT j AND INCREMENT count by 1
  • STEP 7: SET j=j+1
  • STEP 8: PRINT 0
  • STEP 9: SET count =0
  • STEP 10: DECREMENT j by 1
  • Step 11: REPEAT STEP 12 and 13 UNTIL j is greater than 0
  • STEP 12: IF count is less than (i-1)
    PRINT j AND INCREMENT count by 1
  • STEP 13: SET j = j - 1
  • STEP 14: PRINT new line
  • STEP 15: i = i + 1
  • STEP 16: EXIT
