+TASK #1 › Palindrome Number
+Submitted by: Mohammad S Anwar
+You are given a number $N.
+
+Write a script to figure out if the given number is Palindrome. Print 1 if true otherwise 0.
+
+Example 1:
+Input: 1221
+Output: 1
+Example 2:
+Input: -101
+Output: 0, since -101 and 101- are not the same.
+Example 3:
+Input: 90
+Output: 0

+TASK #2 › Demo Stack
+Submitted by: Mohammad S Anwar
+Write a script to demonstrate Stack operations like below:
+
+push($n) - add $n to the stack
+pop() - remove the top element
+top() - get the top element
+min() - return the minimum element

+print $stack->min; # prints -1
