Write code to evaluate whether a chain of inequalities is true or false. An example input is the string
This is true because each of its components is true:
(3<=4) and (4!=9) and (9>3) and (3==3)
A string that represents a chain of one or more inequalities. The allowed comparison operators are
== equals != does not equal > is greater than >= is greater than or equal to < is less than <= is less than or equal to
The allowed numbers are single-digit numbers
9. There won't be any spaces, parentheses, or other symbols.
The correctness of the inequality as a consistent Truthy or Falsey value. Consistent means every Truthy output is the same and every Falsey output is the same.
The intent of this challenge is for you to write code that processes the inequalities, rather than have them be evaluating them as code, even for a single inequality in the chain. As such, methods like Python's
exec that evaluate or execute code are banned. So are functions which look up a method or operator given its name as a string. Nor is it allowed to launching processes or programs to do the evaluation for you.
3<=4!=9>3==3 True 3<=4!=4 False 5>5 False 8==8<9>0!=2>=1 True
