Make big rocks into small rocks Welcome to the grinder. 

Your task is to make big rocks into small rocks by grinding them.

Take an input of a big rock of size n > 3  and grind it.

Continue to grind the rocks by dumping them into the grinder until the size of all the rocks are 2.

rocks are always grinded into equal even halves. If the result of a grinding is odd take result - 1.

Print the output of each grinding as you proceed.

output: 22

The result are two rocks of size 2

input: 50

output:

2424 //two rocks of size 24
12121212 //four rocks of size 12
66666666 //8 rocks of size 6
2222222222222222
