Let A be the number which we get on removing the first of B (A,B both are power of two)
we must have B = 16A and 15A = 10k* N (k = 1,2,.)(N= 1,2 ..)
which gives only 32 and 64
Find all such numbers that are powers of two and on removing its first digit in decimal representation gives another powers of two.
