Substring XOR Queries | Leetcode Weekly Contest 322

Problem :- Substring XOR Queries
Contest :- Leetcode Weekly contest 322
It was a nice problem , you need to observe that it is irrelevant to find Decimal value of substring of length greater than 31 . And we can find the decima value to be searched by doing basic xor operation .

Do let me know any suggestion of yours related any improvement you want me to have :) .

-> 30 second part was cut I don't know how, we will start finding value for smaller length them move to larger length from (1 to 31) . This will make sure we get smallest substring occuring first added in our hasmap/map for particular value 'x' . 11 --> 3 and 011-> 3 but if we go smaller to large we will not consider 011 for 3 .
