Regarding the problem statement

#1

Sir I have a couple of doubts in problem statement.

  1. Where are we using the array?
  2. The number in the range 4-6 was asked in the given example so how the answer is 10?
#2

you have to visualize the array
initially array is empty

now if query of type 0 came you have to insert element into array

after these querys
0 3
0 5
0 10
0 6
array will be [3,5,10,6]

now query type 1 came
1 1 4 6
you have to take array portion from 1 to 4 and take xor with 6
whose xor is max is the ans
3^6 = 5
5^6 = 3
10^6 = 12
6^6 = 0

max ans is 12 for 10 so ans is 10

Oh last element is x in query 1, I thought it is R. Thanks, trying.

#4

The l and r given are the index for the array? If yes, then why is it given 4, it will be out of the index

#5

not 0 zero based index
but 1 based index

r=4 then it means 4th element === 3rd index

Okay, got it sir. thank you.
