Cycling Through Strings

Given two strings, repeatedly cycle through all of the letters in the first string until it is the same length as the second string.

Examples

string_cycling("abc", "hello") ➞ "abcab"

string_cycling("programming", "sample") ➞ "progra"

string_cycling("ha", "good morning") ➞ "hahahahahaha"

Notes

All tests will include valid strings.
