This code is contributed by Nikita Tiwari. Output The integer square root function, or isqrt, is equivalent to floor(sqrt(x)) for non-negative x. For small x, the most convenient way to calculate isqrt is by calling int(x0.5) or int(math.sqrt(x)), but if x is a large enough integer, the sqrt calculation overflows. Abstract.
