Sansa and Xor Hackerrank Problem Solution

PROBLEM STATEMENT

Sansa has an array. She wants to find the value obtained by XOR-ing the contiguous subarrays, followed by XOR-ing the values thus obtained. Determine this value.

Example

Subarray	Operation	Result
3		None		3
4		None		4
5		None		5
3,4		3 XOR 4		7
4,5		4 XOR 5		1
3,4,5		3 XOR 4 XOR 5	2

Now we take the resultant values and XOR them together:

. Return .

Function Description

Complete the sansaXor function in the editor below.

sansaXor has the following parameter(s):

• int arr[n]: an array of integers

Returns

• int: the result of calculations

Input Format

The first line contains an integer , the number of the test cases.

Each of the next  pairs of lines is as follows:
- The first line of each test case contains an integer , the number of elements in .
- The second line of each test case contains  space-separated integers .

SOLUTION IN PYTHON

t=int(input()) for i in range(t): n=int(input()) arr=list(map(int,input().split())) if(n%2==0): print("0") else: result=arr[0] for j in range(2,n,2): result^=arr[j] print(result)
