Given a string A and a string B, count the number of occurrences of string A in B . All of the strings contain only characters.
For example, if A is “ab” and B is "abflskuab"
then your answer should be 2 because A appears in “abflskuab” two times.
Note that if A is “aa” and B is “aaaa”, the number of occurrences of A in B is counted as 3.
You may assume string B is always longer than string A.
The first line of the input is the string A (length of A = 2). The second line is the string B(2 <= length of B <= 9).
The number of occurrences of A appears in B. Note that you DO NOT need to print ‘\n’ at the end of the output.
