Hailstone sequence: Difference between revisions

Output is in hexadecimal but is otherwise correct.

Because of the Game Boy Advance's limited screen size, only the first 4 and last 4 entries are printed to the screen. The emulator's memory dump can show the rest. In addition, the task was split into two separate programs.

===Hailstone Sequence of N equal to 27 ===

===Biggest Sequence Between 2 and 100,000===

To keep this short, I'm only including the part that changed, and the output. This goes after the call to <code>ResetTextCursors</code> but before the infinite loop:

<lang ARM Assembly> mov r0,#1

bl Hailstone

mov r6,r3

mov r0,#2

mov r8,#100000

loop_getBiggestHailstone:

mov r10,r0

bl Hailstone

mov r0,r10

cmp r3,r6

movgt r6,r3 ;if greater than, store in r6

movgt r7,r0 ;if greater than, store in r7

add r0,r0,#1

cmp r0,r8

blt loop_getBiggestHailstone

adr r1,HailstoneMessage_0

bl PrintString

bl NewLine

adr r1,HailStoneMessage_1

bl PrintString

bl NewLine

mov r0,r7

bl ShowHex32

bl NewLine

adr r1,HailStoneMessage_2

bl PrintString

bl NewLine

mov r0,r6

bl ShowHex32

bl NewLine</lang>

{{out}}

<pre>

The number that makes the

biggest sequence is:

00012CE7

And that sequence has a length

of:

0000015F
