Substring Verification

Given two strings, determine whether one string is a substring of the other. A string A is considered a substring of string B if A appears as a contiguous sequence of characters in B.

Note: The comparison is case-sensitive. Formally, let \(s_1\) and \(s_2\) be two strings, the condition to check is whether \(s_1 \subseteq s_2\) or \(s_2 \subseteq s_1\).
