Complete the oddRuns function, which takes a single string argument that contains only Os and 1s. The function counts and returns the total number of odd-length runs (sequences) of Os in the string. A run boundary is marked either by a '1 or by the beginning or end of the string. For example, the string "101111111001000" has 2 odd-length runs of Os: "0" and "000" (there are three runs of Os in all, but the middle run only contains 2 0s, so it doesn't count)
