Write an ARM Assembly code subroutine to approximate the square root of an argument using the bisection method. Your code must approximate the square root of an integer between 0 and 2^(31) -1. Using integer maths is sufficient (no floating point or fractions are required); your code will return the truncated (integer portion) of the square root.

Base your software on the following pseudocode:

INPUT: Argument x, endpoint values a, b, such that a < b OUTPUT: value which differs from sqrt(x) by less than 1 done = 0 a = 0 b = square root of largest possible argument (e.g. ~216). C = -1 do { c_old INPUT: Argument x, endpoint values a, b, such that a < b OUTPUT: value which differs from sqrt(x) by less than 1 done = 0 a = 0 b = square root of largest possible argument (e.g. ~216).
