Maximize XOR by selecting 3 numbers in range [ 0 , A ] , [ 0 , B ] , and [ 0 , C ] respectively | Function to calculate maximum triplet XOR form 3 ranges.
Initialize a variable to store the answer.
create minimum number that have a set bit at ith position.
Check for each number and try to greedily choose the bit if possible If A >= cur then A also have a set bit at ith position.
Increment the answer.
Subtract this value from A.
Check for B.
Increment the answer.
Subtract this value from B.
Check for C.
Increment the answer.
Subtract this value from C.
If any of the above conditions is not satisfied then there is no way to turn that bit ON ..
