Algorithm

  • STEP 1: START
  • STEP 2: SET lines=15
  • STEP 3: Initialize i,j,k,and l
  • STEP 4: SET space=0
  • STEP 5: SET i=1
  • STEP 6: REPEAT STEP 7 TO 20 UNTIL i is less than lines
  • STEP 7: SET j=1
  • STEP 8: REPEAT STEP 9 UNTIL j is less than or equals to space.
  • STEP 9: PRINT " " and SET J=J+1
  • STEP 10: SET j=1
  • STEP 11: REPEAT STEP 12 and 13 UNTIL j is less than or equals to lines
  • STEP 12: IF j is less than equals lines-i PRINT j ELSE PRINT *
  • STEP 13: SET j=j+1
  • STEP 14: DECREMENT j by 1
  • STEP 15: REPEAT STEP 16 and 17 UNTIL j is greater than 0
  • STEP 16: IF j is greater than lines-i PRINT * ELSE PRINT j
  • STEP 17: SET j=j-1
  • STEP 18: IF lines-i is greater than 9 INCREMENT space by 1
  • STEP 19: PRINT new line
  • STEP 20: SET i=i+1
  • STEP 21: EXIT
