--description--

Given a password string, return "weak", "medium", or "strong" based on the strength of the password.

A password is evaluated according to the following rules:

• It is at least 8 characters long.
• It contains both uppercase and lowercase letters.
• It contains at least one number.
• It contains at least one special character from this set: !, @, #, $, %, ^, &, or *.

Return "weak" if the password meets fewer than two of the rules. Return "medium" if the password meets 2 or 3 of the rules. Return "strong" if the password meets all 4 rules.

--hints--

checkStrength("123456") should return "weak".

assert.equal(checkStrength("123456"), "weak");

checkStrength("pass!!!") should return "weak".

assert.equal(checkStrength("pass!!!"), "weak");

checkStrength("Qwerty") should return "weak".

assert.equal(checkStrength("Qwerty"), "weak");

checkStrength("PASSWORD") should return "weak".

assert.equal(checkStrength("PASSWORD"), "weak");

checkStrength("PASSWORD!") should return "medium".

assert.equal(checkStrength("PASSWORD!"), "medium");

checkStrength("PassWord%^!") should return "medium".

assert.equal(checkStrength("PassWord%^!"), "medium");

checkStrength("qwerty12345") should return "medium".

assert.equal(checkStrength("qwerty12345"), "medium");

checkStrength("S3cur3P@ssw0rd") should return "strong".

assert.equal(checkStrength("S3cur3P@ssw0rd"), "strong");

checkStrength("C0d3&Fun!") should return "strong".

assert.equal(checkStrength("C0d3&Fun!"), "strong");
