Problem Statement

There are N non-negative integers written on the blackboard: A_1, ..., A_N.

Snuke can perform the following two operations at most K times in total in any order:

• Operation A: Replace each integer X on the blackboard with X divided by 2, rounded down to the nearest integer.
• Operation B: Replace each integer X on the blackboard with X minus 1. This operation cannot be performed if one or more 0s are written on the blackboard.

Find the number of the different possible combinations of integers written on the blackboard after Snuke performs the operations, modulo 1,000,000,007.

Constraints

• 1 \leq N \leq 200
• 1 \leq A_i \leq 10^{18}
• 1 \leq K \leq 10^{18}
• A_i and K are integers.

There are six possible combinations of integers on the blackboard: (1, 1), (1, 2), (2, 3), (3, 5), (4, 6) and (5, 7). For example, (1, 2) can be obtained by performing Operation A and Operation B in this order.
