# Diffk II

Problem Description

Given an array A of integers and another non negative integer B .

Find if there exists 2 indices i and j such that A[i] - A[j] = B and i != j.

Problem Constraints

1 <= |A| <= 106

0 <= A[i] <= 109

0 <= B <= 109

Input Format

First argument A is an array of integer

Second argument B is an integer

Output Format
Return 1 if two such indexes are found and 0 otherwise

Example Input
Input 1:
```A = [1, 5, 3]
B = 2
```
Input 2:
```A = [2, 4, 3]
B = 3
```

Example Output
Output 1:
```1
```
Output 2:
```0
```

Example Explanation
For Input 1:
```The given value of A[1] = 1 and A[3] = 3.
The value of A[3] - A[1] = 2.
```
For Input 2:
```There are no pairs such that difference is B.
```

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
