Smart Beaver recently got interested in a new word game. The point is as follows: count the number of distinct good substrings of some string s. To determine if a string is good or not the game uses rules. Overall there are n rules. Each rule is described by a group of three (p,l,r), where p is a string and l and r (l≤r) are integers. We’ll say that string t complies with rule (p,l,r), if the number of occurrences of string t in string p lies between l and r, inclusive. For example, string "ab", complies with rules ("ab", 1, 2) and ("aab", 0, 1), but does not comply with rules ("cd", 1, 2) and ("abab", 0, 1).
A substring s[l... r] (1≤l≤r≤|s|) of string s=s1s2... s|s| (|s| is a length of s) is string slsl+1... sr.
Consider a number of occurrences of string t in string p as a number of pairs of integers l,r (1≤l≤r≤|p|) such that p[l... r]=t.
We’ll say that string t is good if it complies with all n rules. Smart Beaver asks you to help him to write a program that can calculate the number of distinct good substrings of string s. Two substrings s[x... y] and s[z... w] are cosidered to be distinct iff s[x... y]≠s[z... w].
Output
Print a single integer − the number of good substrings of string
s.
Note
There are three good substrings in the first sample test: «
aab», «
ab» and «
b».
In the second test only substrings «
e» and «
t» are good.
