Cross adding Unique values

Postby newby12 » Jan 12, 2022 2:12

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

Maybe this should go under Tips and Tricks?

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
    next
   
    goto start
       
sleep
end
