+/**
+ * InfinityString
+ * There is a string, , of lowercase English letters that is repeated infinitely
+ * many times. Given an integer, , find and print the number of letter a's in
+ * the first
+ * 
+ * letters of the infinite string.
+ * 
+ * Example
+ * 
+ * The substring we consider is , the first characters of the infinite string.
+ * There are
+ * 
+ * occurrences of a in the substring.
+ * 
+ * Function Description
+ * 
+ * Complete the repeatedString function in the editor below.
+ * 
+ * repeatedString has the following parameter(s):
+ * 
+ * s: a string to repeat
+ * n: the number of characters to consider
+ * 
+ * Returns
+ * 
+ * int: the frequency of a in the substring
+ * 
+ * Input Format
+ * 
+ * The first line contains a single string,
+ * .
+ * The second line contains an integer,
+ * 
+ * .
+ * 
+ * Constraints
+ * 
+ * For of the test cases,
+ * 
+ * .
+ * 
+ * Sample Input
+ * 
+ * Sample Input 0
+ * 
+ * aba
+ * 10
+ * 
+ * Sample Output 0
+ * 
+ * 7
