For this problem, we are given two triples of nonnegative integers ~(R_1, G_1, B_1)~ and ~(R_2, G_2, B_2)~ and we wish to determine if the tuples ~(\lfloor \sqrt{R_1} \rfloor, \lfloor \sqrt{G_1} \rfloor, \lfloor \sqrt{B_1} \rfloor)~ and ~(\lfloor \sqrt{R_2} \rfloor, \lfloor \sqrt{G_2} \rfloor, \lfloor \sqrt{B_2} \rfloor)~ are identical.

Most programming languages have a function that takes in a nonnegative number and outputs the square root of that number as a floating-point number. Similarly, most languages will allow you to cast that floating-point number to an integer which will remove the decimal part of the number.

Therefore, to check if ~x_1~ and ~x_2~ will be the same, we can compute (int)sqrt(x_1) and (int)sqrt(x_2) and see if they are equal, and repeat this for each of the other pairs of numbers that we need to compare.
