Six-digit **passcodes** The **passcode** you use on your TouchID-enabled**iPhone** and iPad will now have six digits insteadof four.

Beside above, how many 6 digit codes are there? Similarly, if all **the digits** from 1 to 9wereallowed (with no **digit** repeated), then **the**answerwould be 9*8*7***6***5*4 = 60480. **The** tricky partcomeswhen **the digit** 0 is allowed: suppose that you wanted toforma **6**-**digit** number using **digits** from0,1,,9without repeating a **digit**.
