 # Given a string s, check if it can be constructed by taking a substring of
 # it and appending multiple copies of the substring together.
 
+# Example 1:
+#
+# Input: s = "abab"
+# Output: true
+# Explanation: It is the substring "ab" twice.
+#
+# Example 2:
+#
+# Input: s = "aba"
+# Output: false
+#
+# Example 3:
+#
+# Input: s = "abcabcabcabc"
+# Output: true
+# Explanation: It is the substring "abc" four times or the substring "abcabc" twice.
