Neutron number string string appears calculated.

/ * 
Calculate the number of neutrons string string appears. 
Algorithm: the longest match string, the following is an illustration: 
ABCABCABC 
ABC 
looping through letter string before lenT-lenP; 
loop through the string, with the substring point j, k with the recording position of the letter string begins each trip, if the p [ j] == t [k] is k, j are after the shift 
when the length of the substring j == lenP, a substring is found, the number of ++.
