Floating point numbers don't have bits at the level of value-representation ... WebSo already some bits will be on and we have set the 2nd bit on that is called merging. Checking whether a bit is on or off is known as masking. So, these two operations we have seen in Bitwise operations: left shift, masking and merging. All these operations we will use now for finding duplicates in a string.
