Xor sum

n, q = [int(x) for x in input().split()]

array = [int(x) for x in input().split()]

for i in range(1, n):
    # print('Something', array[i], array[i-1], array[i] ^ array[i-1])
    array[i] = array[i] ^ array[i-1]

print(array)
output = []
for i in range(q):
    a, b = [int(x) for x in input().split()]
    if a == 1: output.append(str(array[b-1]))
    else: output.append(str(array[b-1] ^ array[a-2]))

print("\n".join(output))
