先來個只計算分割數的版本
int
?Compute(
int
?number,?
int
?maximum)
{
????
if
?(number?
==
?
1
?
||
?maximum?
==
?
1
)
????????
return
?
1
;
????
else
?
if
?(number?
<
?maximum)
????????
return
?Compute(number,?number);
????
else
?
if
?(number?
==
?maximum)
????????
return
?
1
?
+
?Compute(number,?maximum?
-
?
1
);
????
else
????????
return
?Compute(number,?maximum?
-
?
1
)?
+
?Compute(number?
-
?maximum,?maximum);
}
int
?IntPartionNo(
int
?n)
{
????
return
?Compute(n,?n);
}
打印所有分割版本
int
?IntegerPartition(
int
?n)
{
????
int
?
*
partition?
=
?
new
?
int
[n]();
????
int
?

repeat?
=
?
new
?
int
[n]();
????partition[
1
]?
=
?n;
????repeat[
1
]?
=
?
1
;
????
int
?count?
=
?
1
;
????
int
?part?
=
?
1
;
????
int
?last,?smaller,?remainder;
????printf(
"
%3d

,?partition[
1
]);
????
do
?
????
{
????????last?
=
?(partition[part]?
==
?
1
)?
?
?(repeat[part
--

+
?
1
)?:?
1
;
????????smaller?
=
?partition[part]?
-
?
1

????????
if

????????????

repeat[part
++

????????partition[part]?

?smaller;
????????repeat[part]?
=

????????
if

0

????????
{
????????????partition[

????????????repeat[part]?
=
?
1

????????}
????????
++
count;
????????printf(
"

);
????????
for
?(
int

1
;?i?

++
i)
????????????
for
?(
int
?j?
=
?
1
;?j?

++

????????????????printf(

,?partition[i]);
????}
?
while

????
if

}
沒有時間把解釋寫出來，自己根據變量名結合網上原理湊合看吧，真是對不起觀眾啊
