According to Java standard library documentation, the hash code of String is computed as
s*31 ^ (n -1) + s*31 ^ (n -2) + ... + s[n -1]
s[i] is the i-th character of the string,
n is the length of the string, and
^ indicates exponentiation. Computation uses signed 32-bit integers in two’s complement form.
Heather is going to hack the servers of Not Entirely Evil Recording Company (NEERC). To perform an attack she needs k distinct query strings that have equal hash codes. Unfortunately, NEERC servers accept query string containing lower- and uppercase English letters only.
Heather hired you to write a program that generates such query strings for her.
The single line of the input file contains integer k — the number of required query strings to generate (2 ≤ k ≤ 1000).
Output k lines. Each line should contain a single query string. Each query string should be non-empty and its length should not exceed 1000 characters. Query string should contain only lower- and uppercase English letters. All query strings should be distinct and should have equal hash codes.
