You are given an integer n (it may be negative).
Return True if n has exactly three decimal digits, and False otherwise. Ignore the sign, so judge by the absolute value of n.
In other words, return True when the absolute value of n lies between 100 and 999 inclusive.
NOTE: This is a function-type question — you only write the function. Do not read input or print anything; a hidden checker calls your function and checks its return value.
