+/* Actually found a neat math solution to make this one quicker
+ * since (a + b + c) = 1000
+ * and a^2 + b^2 = c^2
+ *
+ * We can say:
+ * c = 1000 - (a + b)
+ * c^2 = (1000 - (a + b))^2
+ * and
+ * a^2 + b^2 = (1000 - (a + b))^2
+ * So you need to find an a and b that satisfy this
+ * We know a and b are less than 500 since c must be larger
