Dripping water wears away stone is an idiom, which originated from the 《Chinese book • Meicheng biography》by Ban Gu of the Eastern Han Dynasty.
The idiom means that water drops continuously, can drop through the stone; persistence in metaphor, subtle power can also achieve the difficult work.
It is assumed that M drops of water can penetrate a 1 micron thick stone. How many drops of water does it take for a given N micron thick stone to break through?
The input is twopositive integers M (1<=M<=1000000) and N (1<=N<=100), whichrepresent the number of water droplets required to breakdown a 1 micron thickstone and the thickness of the stone respectively.
The output is apositive integer, that is, the number of water droplets required to break downa stone of N microns thick.
