@Hk199977,
hello harsh,
p=p<<1 means p=p*2 .

let consider a binary number 1011 now we want to convert it to decimal .
how will do that we go to each position if that position bit is set then we add 2^(position-1).
bhaiya is calculating 2^(position-1) using p

for position equal 1 p is equal to 1
for position equal 2 p is equal to 2
for position equal 3 p is equal to 4
for position equal 4 p is equal to 8
so on
