有人可以帮我将这段 Python 代码翻译成 Oz 语言吗?
def rep_subset_conditional(S, tset, index, t, count):
for i in xrange(index, len(S)):
tset += [S[i]]
tsum = sum(tset)
if tsum == t:
print tset
count += 1
tset.remove(S[i])
return count
elif tsum > t:
tset.remove(S[i])
return count
else:
count=rep_subset_conditional(S, tset, i, t, count)
tset.remove(S[i])
return count
此代码仅计算并打印总和等于 t 的给定集合的所有子集(元素重复)。下面是这段代码的试运行:
>>> rep_subset_conditional([1, 5, 10, 25, 50], [], 0, 10, 0)
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
[1, 1, 1, 1, 1, 5]
[5, 5]
[10]
4
t
这里是 10
S
是[1, 5, 10, 25, 50]
我想把这个程序翻译成 Oz 的子集。但我无法正确地做到这一点。请帮忙!这就是我所尝试的:
declare Rep T1 T2 Sum
fun {Rep L S MainList AuxList C}
case L of nil then C
[] H|T then
{Browse H|AuxList}
if {Sum H|AuxList} == S then
T1={Rep MainList S MainList H|AuxList C+1}
{Rep T S MainList AuxList T1}
else
if {Sum H|AuxList} < S then
T2 = {Rep MainList S MainList AuxList C}
{Rep T S MainList AuxList T2}
end
end
end
end
fun {Sum L}
case L of nil then 0
[] H|T then
H + {Sum T}
end
end
