A safe and vault lock needs to be open.

there are 100 numbers on the dial. ( 0~99 )

The cue is the numbers are whole numbers. (includes zero)

The 3 numbers must be in order to open up the lock

... eg , 40,60,90 not the same as 90 ,60 ,40

Numbers may be repeat,

eg : 20, 20, 80 or 20 80 20 or 20 20 20

In total, how many possible sets of numbers are there ?

Pls show maths workings, and thanks !
