Problem 44523. Pattern Sum
Write a function which receives two single digit positive integers, (k and m) as parameters and calculates the total sum as: k + kk + kkk + .... (the last number in the sequence should have m digits) For example, if the two integers are: (4, 5). Your function should return the total sum of: 4 + 44 + 444 + 4444 + 44444. Notice the last number in this sequence has 5 digits. The return value should be 49380.
