Answer 1

l is a list containing 1*3, 2*3, 3*3, 4*3, 5*3, 6*3... .upto 16*3

m is a list containing 3&1, 6&1, 9&1, 12&1, 15&1, 18&1, ........upto 48&1

u probably have a doubt in the ''&" operator..

its nothing but BITWISE AND OPERATOR...LIKE IN AND GATE . ..

eg..
8&2
=>binary(8) and binary(2)
=>1000 and 0010
=>=>=>multiply bit by bit...
=>0000

now.. 12&1
=>1100 and 0001
=>0000(bit by bit multiplicatiin)

perform this operation and will get expected output...
