Not understanding line of code

#1

in this code please explain me the line number 45 that is ans|=sum<<i; with an example. I am very confused with this line

#2

hello @shivamgoel150

it basically sets ith bit of ans.
becuase sum is 1.
sum<<i will give a number whose ith bit will be set .
ans|=sum<<i ; will set the ith bit of ans by taking or with it.

btw ur logic seems incorrect to me
