Asked in company
Alice has two numbers, 'X' and 'Y'. He is asked to perform the following operations any number of times.
Alice adds 1 to 'X' if 'X' is odd. Alice adds 2 to 'X' if 'X' is even. Will he be able to make 'X' equal to 'Y'?
Return 1 if 'X' can be made equal to 'Y' using the above operations any number of times(possibly 0) and 0 otherwise.
Note: Assume 1-based indexing.
For example:
Let 'X' = 3 and 'Y' = 6, Alice adds 1 to 'X' since 'X' is odd. Now 'X' will become 4. Then, Alice will add 2 to 'X', since 'X' is even, and it will become 6. 'X' becomes equal to 'Y'. Hence we will return 1 as the answer.
Problem approach
For example, input is 4567 explanation: - Odd positions are 4 and 6 as they are pos: 1 and pos: 3, both have sum 10. Similarly, 5 and 7 are at even positions pos: 2 and pos: 4 with sum 12. Thus, the difference is 12 – 10 = 2
