解题思路:

注意事项:

参考代码:

while True:
    try:
        a=input().strip()
        b=input().strip()
        if len(b)>len(a):
            print('no')
        else:
            s=0
            l=len(a)
            step=0
            while step<=l:
                a=a[1:]+a[0]
                #print(a)
                if b in a:
                    print('yes')
                    s=1
                    break
                step+=1
            if s ==0:
                print('no')
    except:
        break
