Write a function str2int to convert a string to an integer (assume that the number is always valid)
str2int("1234") → 1234, str2int("~1234") → ~1234
Write a function pairStar to form a new string where identical chars that
are adjacent in the original string are separated from each other by a "*"
pairStar("xxyy") → "x*xy*y", pairStar("aaaa") → "a*a*a*a"
