A run of symbols in a string is a substring of at least two consecutive occurrences of the symbol but it can be longer. For example aababbbab has a run of 3 bs and a run of 2 as (aababbbab) and abab has no runs. For = {a, b}, construct DFAs that accept the language:

L = { w | w contains no runs of length less than or equal to three}

L = { w | w contains at most two runs of as length three}
