仍然是公式求解:
a/b = 1/(p1+1) + (a-r1)/b*(p1+1)
其中:
p1 = b/a
r1 = b%a
更新:
a = a-r1
b = b*(p1+1)
终止循环条件:
- a==1:
除到头了,t=a/b
- b%a==0:
a 可以被 b 整除,这个时候 t =1 /(b/a) = 1/ p1
while True:
try:
a,b = list(map(int,input().split('/')))
flag = True
t=[]
while flag:
p = int(b/a)
r = int(b%a)
if r==0 and a > 1:
t.append('1'+'/'+ str(p))
flag=False
elif a==1:
t.append('1'+'/'+ str(b))
flag = False
else:
t.append('1'+'/'+ str(p+1))
a = a-r
b = b*(p+1)
print("+".join(t))
except:
break
