Algorithm
space(i)
step 1: start
step 2: check whether i>=0,then go to step 3
else go to step 5
step 3: print " "
step 4: i=i-1
step 5: stop
floyd(n)
step 1: start
step 2: intilize x<-1,num<-1
step 3: check whether n>0 then go to step4
else go to step16
step 4: check whether num>9 then go to step5
else go to step 6
step 5: call space(n-2)
step 6: call space(n)
step 7: intilize i<-0
step 8: check whether i<x then go to step9
else go to step 13
step 9: print num
step 10: num=num+1
step 11: i=i+1
step 12: go to step 8
step 13: x=x+1
step 14: go to new line
step 15: n=n-1
step 16: stop
main()
step 1:start
step 2: call floyd(13)
step 3: stop
