Problem Statement

We have N bulbs arranged on a number line, numbered 1 to N from left to right.
Bulb i is at coordinate i.

Each bulb has a non-negative integer parameter called intensity.
When there is a bulb of intensity d at coordinate x, the bulb illuminates the segment from coordinate x-d-0.5 to x+d+0.5.
Initially, the intensity of Bulb i is A_i. We will now do the following operation K times in a row:

For each integer i between 1 and N (inclusive), let B_i be the number of bulbs illuminating coordinate i. Then, change the intensity of each bulb i to B_i.

Find the intensity of each bulb after the K operations.

Constraints

1 \leq N \leq 2 \times 10^5

1 \leq K \leq 2 \times 10^5

0 \leq A_i \leq N

Input

Input is given from Standard Input in the following format:

N K
A_1 A_2 \ldots A_N

Output

Print the intensity A{'}_i of each bulb i after the K operations to Standard Output in the following format:

A{'}_1 A{'}_2 \ldots A{'}_N

Sample Input 1

5 1
1 0 0 1 0

Sample Output 1

1 2 2 1 2

Initially, only Bulb 1 illuminates coordinate 1, so the intensity of Bulb 1 becomes 1 after the operation.
Similarly, the bulbs initially illuminating coordinate 2 are Bulb 1 and 2, so the intensity of Bulb 2 becomes 2.

Sample Input 2

5 2
1 0 0 1 0

Sample Output 2

3 3 4 4 3

import copy
import math
N, K = map(int, input().split())
A = list(map(int, input().split()))

if math.ceil(math.log2(N // 10)) * 3 + 6 < K:
    A= [N]*N
else:
    for _ in range(K):
        B = [0] * N
        for i in range(N):
            if A[i] >= 0:
                if (A[i] >= max(N - i, i)):
                    B = list(map(lambda x: x+1, B))
                else:
                    B[i] += 1
                    for j in range(A[i]):
                        if (i - j - 1 >= 0):
                            B[i-j-1] += 1
                        if (i + j + 1 < N):
                            B[i+j+1] += 1
        A = copy.copy(B)

for _ in A:
    print(_, end=' ')
