The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants.
The function first discards as many whitespace characters as necessary until the first non-whitespace character is found. Then, starting from this character, takes an optional initial plus or minus sign followed by as many numerical digits as possible, and interprets them as a numerical value.
