Problem Statement
You are given an integer sequence $A = (A_1, \dots, A_N)$ of length N, and integers M and K.
For each $i = 1, \dots, N - M + 1,$ solve the following independent problem.
Find the sum of the first K values in the sorted list of the $M integers A_i, A_{i + 1}, \dots, A_{i + M - 1}$ in ascending order.
Input
The input is given from Standard Input in the following format:
N M K
$A_1 A_2 \ldots A_N$
Output
Let $\mathrm{answer}_k$ be the answer to the problem for i = k, and print them in the following format:
$\mathrm{answer}_1 \mathrm{answer}_2 \ldots \mathrm{answer}_{N-M+1}$
Constraints
- $1 \leq K \leq M \leq N \leq 2 \times 10^5$
- $1 \leq A_i \leq 10^9$
- All values in the input are integers.

- For i = 1, sorting A_i, A_{i+1}, A_{i+2}, A_{i+3} in ascending order yields 1, 1, 3, 4, where the sum of the first three values is 5.
- For i = 2, sorting A_i, A_{i+1}, A_{i+2}, A_{i+3} in ascending order yields 1, 1, 4, 5, where the sum of the first three values is 6.
- For i = 3, sorting A_i, A_{i+1}, A_{i+2}, A_{i+3} in ascending order yields 1, 4, 5, 9, where the sum of the first three values is 10.
