I got an interview question yesterday but it had no description as it was all verbal. It was along the lines of:

Given a string, see how many possible runs there are using the seen characters in the string in the order they appear.

So if you are given a string = "abcabc", there are 4 possible runs of "abc".

abcabc
abc___
ab___c
a___bc
___abc

I can't find out the problem on the site and was wondering if anyone could help me find a solution to this.

def howManyRuns(s):
    if len(s) < 2:
        return len(s)
    hashmap = {}
    for i in range(len(s)):
        if i == 0:
            hashmap[s[i]] = 1
        else:
            if s[i] in hashmap:
                hashmap[s[i]] += hashmap[s[i - 1]]
            else:
                hashmap[s[i]] = 1
    return hashmap[s[-1]]

Is the code that I have thus far.
