AnswersPlease write a function that accepts a floating number and returns its square-root. You may not use built-in square root function from your language. However, basic operators like addition, subtraction, multiplication are allowed. Please take into consideration the floating precision.

AnswersI have a log that consists of more than 100 million lines. Each line is just a data about user login, login time, etc. I want to sort them based on user login, and then if there is a tie based on login time, etc. However, I have limited memory, so don't think of storing all of them in an array. The memory can only hold n data where n is much smaller than 100 millions. You can access the disk though although it is much slower. How will you do it so that it is as efficient as possible?
