When nextGuess and lastGuess are almost identical, nextGuess is the approximated square root. The initial guess can be any positive value (e. g., 1). This value will be the starting value for lastGuess. If the difference between nextGuess and lastGuess is less than a very small number, such as 0.0001, you can claim that nextGuess is the approximated square root of n. If not, next- Guess becomes lastGuess and the approximation process continues. Imple- ment the following method that returns the square root of n.
