I was playing around with numbers..

I managed to write a program that builds two 4 digit numbers with values between 0 an 9..
It cross adds all the digits , and picks out the two 4 digit sets , that equate to all 16 unique values...

Code: Select all

'Program to build two 4 digit numbers that when cross added or cross multiplied results in 16 unique values.

screen 19

dim as string n1
dim as ubyte v1 , v2

dim as string dict1 = ""
dim as string dict2 = ""
dim as string got_it = ""

dim as longint count = 0
dim as ubyte check

goto redo

start:

for b as ubyte = 0 to 2
for c as ubyte = b to 3
if dict1[c] < dict1[b] then swap dict1[b] , dict1[c]
if dict2[c] < dict2[b] then swap dict2[b] , dict2[c]
next
next

cls
print
print "Added unique values = " ; got_it
print
print "Four digits 1 = " ; dict1
print "Four digits 2 = " ; dict2
print
print "Press key for next round.. or press esc to exit"
sleep
if inkey = chr( 27 ) then end

print "WORKING!!!"

redo:

count = 0
got_it = ""
dict1 = ""
dict2 = ""

do
randomize
v1 = int( rnd * 10 )
if instr( 1 , dict1 , str( v1 ) ) = 0 then dict1+= str( v1 )
loop until len( dict1 ) = 4

do
randomize
v2 = int( rnd * 10 )
if instr( 1 , dict2 , str( v2 ) ) = 0 then dict2+= str( v2 )
loop until len( dict2 ) = 4

check = 0
for b as ubyte = 1 to 4
v1 = val( mid( dict1 , b , 1 ) )
for c as ubyte = 1 to 4
v2 = val( mid( dict2 , c , 1 ) )
n1 = right( "00" + str( v1 + v2 ) , 2 )
if instr( 1 , got_it , n1 ) = 0 then got_it+= n1 + " " : check+= 1
next
next

if check <> 16 then goto redo

goto start

sleep
end

I rewrote it with Hex chrs...

Now it does 1 string of 5 digits and 1 string of 4 digits..
There's 30 cross added unique values. And it picks out 20 of them..

Code: Select all

screen 19

dim as string n1
dim as ubyte v1
dim as ubyte v2

dim as string dict1 = ""
dim as string dict2 = ""
dim as string got_it = ""

print
print "WORKING!!!"

goto redo

start:

for b as ubyte = 0 to 3
for c as ubyte = b to 4
if dict1[c] < dict1[b] then swap dict1[b] , dict1[c]
next
next
for b as ubyte = 0 to 2
for c as ubyte = b to 3
if dict2[c] < dict2[b] then swap dict2[b] , dict2[c]
next
next

cls
print
print "Cross adeed unique values = " ; got_it
print
print "Set 1 = " ; dict1
print "Set 2 = " ; dict2
print
print "Press key for next round.. or press esc to exit"
sleep
if inkey = chr( 27 ) then end

print
print "WORKING!!!"

redo:

if inkey = chr( 27 ) then end

got_it = ""
dict1 = ""
dict2 = ""

do
randomize
v1 = int( rnd * 16 )
if instr( 1 , dict1 , hex( v1 ) ) = 0 then dict1+= hex( v1 )
loop until len( dict1 ) = 5

do
randomize
v2 = int( rnd * 16 )
if instr( 1 , dict2 , hex( v2 ) ) = 0 then dict2+= hex( v2 )
loop until len( dict2 ) = 4

for b as ubyte = 1 to 5
v1 = val( "&H" + mid( dict1 , b , 1 ) )
for c as ubyte = 1 to 4
v2 = val( "&H" + mid( dict2 , c , 1 ) )
n1 = right( "00" + str( v1 + v2 ) , 2 )
if instr( 1 , got_it , n1 ) = 0 then
got_it+= n1 + " "
else
goto redo
end if
next

goto start

sleep
