+// Given an integer x, return true if x is a
+// palindrome
+// , and false otherwise.
+
+// Example 1:
+
+// Input: x = 121
+// Output: true
+// Explanation: 121 reads as 121 from left to right and from right to left.
+// Example 2:
+
+// Input: x = -121
+// Output: false
+// Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.
+// Example 3:
+
+// Input: x = 10
+// Output: false
+// Explanation: Reads 01 from right to left. Therefore it is not a palindrome.
+
+// Constraints:
+
+// -231 <= x <= 231 - 1
+
+// Follow up: Could you solve it without converting the integer to a string?
+
+//More examples for me
+//madam
+//121
+//101
+//aba
+//202
