+### Power of Pow | Even Number
+
+Ref: [link](https://practice.geeksforgeeks.org/problems/power-of-pow-even-number/0/?ref=self)
+
+Given a single integer N, your task is to find the sum of the square of first N even natural Numbers.
+
+Examples:
+
+Input : 3
+Output : 56 
+22 + 42 + 62 = 56
+
+Input : 8

+22 + 42 + 62 + 82 + 102 + 122 + 142 + 162 
+Input:
+First line of the input contains an integer T, denoting the number of test cases. Then T test case follows. The only line of each test case contains an integer N.
+
+Output:
+For each test case output the required anser on a new line.
+
+Constraints:
+1<=T<=100
+N<=104
+
+Example:
+Input:

+Input:
+First line of the input contains an integer T, denoting the number of test cases. Then T test case follows. The only line of each test case contains an integer N.
+
+Output:
+For each test case output the required anser on a new line.
+
+Constraints:
+1<=T<=100

+### isogram
+
+Ref: [link](https://practice.geeksforgeeks.org/problems/check-if-a-string-is-isogram-or-not/0/?ref=self)
+
+Given a word or phrase, check if it is isogram or not. An Isogram is a word in which no letter occurs more than once.
+
+Input:
+
+The first line of input contains an integer T denoting the number of test cases. Each test case consist of one strings in 'lowercase' only, in a separate line.
+Output:
+
+Print 1 if string is Isogram else print 0.
+Constraints:
+
+1 <= T <= 100
+
+1 <= |S| <= 100
+Example:
+
+Input:
+
+2
+
+machine
+
+geeks
+
+Output:
+
+1
+
+0
+
+Explanation:
+For testcase 2: geeks is not an isogram as 'e' appears twice. Hence we print 0.
