hello @Somasree

clear bit at position i means we want to make its value 0.

update bit at position i with v means we want to update its value to v.

for example->
1101 -> if i clear the third bit (from right) then it will become 1001

1101 -> if i update second bit (from right) with 1 then it will become 1111
