string , charFreq(), and an other one which iterate through a
vector line by line looking for last element on each line, last().
The problem is, after appending all chars in a string and try to
count clusters of values in that string, I get seg fault. I feel
like my logic behind is ok, but I am not sure what I did wrong. Can
someone help...
