# Can we shift string A to string B?

Given two strings A and B, return whether or not string A can be shifted some number of times to get B. A `shift` operation is described as moving the characters of a string forward or backwards without changing the order of characters in the string. i.e given string `xyz`, if we shift it once, we get `zyx` (`z` shifted right and hence moved to first position, so it shifted `x` which was first position, to second position and hence `y` got moved to third position from second position, giving us `zyx`).

Write a function `solve` which accepts the following parameter(s):
1.) A = a string
2.) B = a string

Example
Input:
`A = abcde`
`B = cdeab`
Output:
`True`

Explanation
• Example 1: string A `abcde`, string B `cdeab`
• Shift it right once, we get `eabcd`
• Shift it right again, we get `deabc`
• Shift it right again, we get `cdeab` which is same as target string B `cdeab`. Hence we return `True`.

Example Input:
`A = abc`
`B = acb`
Output:
`False`

Explanation • Example 2: string `abc`, string B `acb`
• Shift it right once, we get `cab`
• Shift it right again, we get `bca`
• Shift it right again, we get `abc` which is the original string that we started with, which means we cannot convert it to target string B `acb`. Hence we return `False`.

Constraints
• The length of the string A will be greater than 0 and less than 1000.
• The length of the string B will be greater than 0 and less than 1000.
