+# Dimik - Even Odd 1
+
+In this problem, you will be given `T` testcases.Each line of the testcase consist of an integer `n`.We have to determine whether `n` is even or odd.
+
+### Solution 
+* If n is divisible by 2
+  * its a even number so print 'even'
+* if its not divisible by 2 
+  * its a odd number so print 'odd'
+
+### C++
+```cpp
+#include <bits/stdc++.h>
+using namespace std;
+int main()
+{
+    int t;
+    cin >> t;
+    for (int k = 1; k <= t; k++)
+    {
+        int n;
+        cin >> n;
+        if (n % 2)
+            cout << "odd" << endl;
+        else
+            cout << "even" << endl;
+    }
+}
+```
