+##===================================
+#
+#Given two non-negative integers num1 and num2 represented as string, return the sum of num1 and num2.
+#
+#Note:
+#
+#The length of both num1 and num2 is < 5100.
+#Both num1 and num2 contains only digits 0-9.
+#Both num1 and num2 does not contain any leading zero.
+#You must not use any built-in BigInteger library or convert the inputs to integer directly.
+class Solution:
+    def addStrings(self, num1, num2):
+        tmp = int(num1) + int(num2)	#Initialize tmp and convert the numbers to int
+        return str(tmp)	#We return str of tmp
