The problem is 2^(axxxx) where x belongs to {0,1,.....9} & a
belongs to {1,2,3,.....9}. This is clearly not equivalent to
2*(axxxx).

The solution will be easier if we can give the answer in
HEXADECIMAL format.

2^2=(4)DEC=(100)BINARY=(4)HEX
2^4=(16)DEC=(10000)BINARY=(10)HEX
2^7=(128)DEC=(10000000)BINARY=(80)HEX
.
.
.
2^n=(X)DEC=(100.....0)BINARY{n no. of zero after 1}=(Z)HEX
(X is the decimal of 2^n, Z is HEXADECIMAL of 2^n)

To get Z get HEX of (1a) where a = n%4 is the number of
zeros after 1.

Then path n/4 no. of zeros with that.

can anyone suggest the code for integer representation of
2^n , (where n is any integer), with polynomial time
complexity ?

Why isn't any of this standardized in c? Any real program has to do some of these things.
