Given a list S consisting of strings separated by a space. Hash the list using the hash rule and a long string X given below and return the hash value.
String X: "abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ".
Hash Rule: Hash is the summation of all the character values in the input: (currentIndex + (position of the character In the string initial) ). And then this hash is multiplied by the number of strings in the list.

Example 1:
Input:
S = aA1 b
Output:
132
Explanation:
List is ["aA1", "b"]
a: 0 + 0 = 0
A: 1 + 36 = 37
1: 2 + 26 = 28
b: 0 + 1 = 1
So, 2(0+1+37+28) = 2(66) = 132
Example 2:
Input:
S = aa BB cc DD
Output:
640
Explanation:
List is ["aa", "BB","cc","DD"]
a: 0 + 0 = 0
a: 1 + 0 = 1
B: 0 + 37 = 37
B: 1 + 37 = 38
c: 0 + 2 = 2
c: 1 + 2 = 3
D: 0 + 39 = 39
D: 1 + 39 = 40
So, 4(0+1+37+38+2+3+39+40)= 4(160)=640

Your Task:
You don't need to read input or print anything. Your task is to complete the function hashString() which takes string S, list of space-separated strings as a parameter and returns the hash value of the list.

Expected Time Complexity: O(Sum of the length of all the strings)
Expected Auxiliary Space: O(Length of initial string)

Constraints:
1 ≤ Length of a string ≤ 30
1 ≤ Number of strings in a list ≤ 20
