CF1396A Multiples of Length

You are given an array $ a $ of $ n $ integers. You want to make all elements of $ a $ equal to zero by doing the following operation exactly three times: - Select a segment, for each number in this segment we can add a multiple of $ len $ to it, where $ len $ is the length of this segment (added integers can be different). It can be proven that it is always possible to make all elements of $ a $ equal to zero.

The first line contains one integer $ n $ ( $ 1 \le n \le 100\,000 $ ): the number of elements of the array. The second line contains $ n $ elements of an array $ a $ separated by spaces: $ a_1, a_2, \dots, a_n $ ( $ -10^9 \le a_i \le 10^9 $ ).

The output should contain six lines representing three operations. For each operation, print two lines: - The first line contains two integers $ l $ , $ r $ ( $ 1 \le l \le r \le n $ ): the bounds of the selected segment. - The second line contains $ r-l+1 $ integers $ b_l, b_{l+1}, \dots, b_r $ ( $ -10^{18} \le b_i \le 10^{18} $ ): the numbers to add to $ a_l, a_{l+1}, \ldots, a_r $ , respectively; $ b_i $ should be divisible by $ r - l + 1 $ .
