+# Find Second largest element in an array
+
+Given an array of integers, our task is to write a program that efficiently finds the second largest element present in the array.
+
+## Input Format
+
+First line contains T that denotes the number of test cases. This is followed by T lines, each containing an integer, N.
+
+
+## Output Format
+
+Print the required answer for each test case.
+
+
+### Sample Input and Output
+
+```
+Input : arr[] = {12, 35, 1, 10, 34, 1}
+Output : The second largest element is 34.
+
+Input : arr[] = {10, 5, 10}
+Output : The second largest element is 5.
+
+Input : arr[] = {10, 10, 10}
+Output : The second largest does not exist.
+
+```
