Hey @akshpreetsinghs
So basically u have to tell the first set bit which is on

Say for 3 its binary is 00000…0011 so here first 1 is rightmost so
its indexed 1

FOr 8 binary is 000…001000 so its index is 4

#3

so in here 3 has 011 the right most set bit indexed pos is 0 , right?

#4

yeah if answer should begin from 0 then 0 indexed

if answer is supposed to begin from1 then 1 indexed
