+"""Given a non-negative integer x, return the square root of x 
+rounded down to the nearest integer. 
+The returned integer should be non-negative as well.
+You must not use any built-in exponent function or operator.
+For example, do not use pow(x, 0.5) in c++ or x ** 0.5 in python."""

+# Solution
+import math 
+def mySqrt(x):
+    if x <= 0:
+        return 0
+    else:
+        return int(math.sqrt(x))
+# check    
+print(mySqrt(8)) # Output  -> 2
+print(mySqrt(-1)) # Output -> 0
+print(mySqrt(0)) # Output  -> 0
+print(mySqrt(999)) #Output -> 31
