Adjacent Duplicate Checker

Given a string s, determine whether it contains at least one pair of identical characters positioned adjacently. In other words, check if there exists an index \(i\) such that \(s_i = s_{i+1}\). If such a pair exists, output True; otherwise, output False.

Note: For an empty string or a string with a single character, the output should be False.

inputFormat

The input is provided through stdin as a single string s. This string can include letters, symbols, or even be empty.
