Last and Second-Last

Return a new string made of the last character of the string, one ordinary space, and the second-to-last character.

输入格式

The input is one JSON string whose length, counted in Unicode code points, is 2..100 (the original length bound). The source does not restrict the character set; this site allows all Unicode scalar values, including whitespace, NUL, and non-BMP characters, but no lone surrogate code points. Characters are preserved through JSON encoding, and the input is ≤1230 bytes.

输出格式

Output one canonical ASCII JSON string with no extra whitespace; a trailing newline is optional. Printable ASCII other than double quotes and backslashes is output as is (including /); double quotes and backslashes are each escaped; backspace, form feed, newline, carriage return, and tab use \b, \f, \n, \r, \t respectively; other control characters, DEL, and non-ASCII characters use lowercase four-digit \uXXXX, and non-BMP characters use lowercase UTF-16 surrogate pairs. The surrounding double quotes must be kept; this is equivalent to Python json.dumps(value,ensure_ascii=True).
