100011= 1*2^5+0*2^4 + 0*2^3+0*2^2 + 1*2^1+1*2^0.
= 32+0+0+0+2+1 = 35.

111 in decimal is 7 and 101 in decimal is 5.
now multiply 7 and 5 ie. 7*5=35.
Next, convert 35 into binary by using 32-bit representation.
32 16 8 4 2 1.
1 0 0 0 0 1 (32+2+1=35 so put 1 in place of 32,2,1 and 0 in remaining places).
