Problem statement

Given an array S of N length consisting of only binary numbers (0 or 1). We need to decompose S into K consecutive non-empty subarrays such that every element is present in only one subarray.

Say subarrays are S[1], S[2], S[3], .... , S[K]. Choose an array B , which is a permutation of 1 to K i.e. it is of size K and include every element from 1 to K.

Now , form a new array V = S[B[1]] + S[B[2]] + ......  + S[B[K]]. 

Suppose, X is equal to the count of subarrays in V such that sum of elements in the subarray is greater than the Floor(length of the subarray / 2).

Aim is to maximize X.

Input format :

• First line contains two space-separated integers : N and K 
• Second line contains N space-separated integers denoting array S.

Output format :

• In the first K lines, print one integer denoting end index of i-th subarray (indexes are 1 based).
• In next line print K space separated integers, denoting array B (permutation of 1 to K)
• End index of subarray should be in increasing order.

Verdict and scoring :

• Your score is equal to the sum of the values of all test files. The value of each test file is equal to the value of X that you found.

  If decomposition of array S is invalid, or array B is invalid you will receive a wrong answer verdict.

Constraints :

• $N = 10^3$
• $50 \le K \le 10^2$
