Turn off the rightmost set bit | GeeksforGeeks
Write a C function that unsets the rightmost set bit of an integer.
Let the input number be n. n-1 would have all the bits flipped after the rightmost set bit (including the set bit). So, doing n&(n-1) would give us the required result.
int
fun(unsigned
int
n)
{
return
n&(n-1);
}
