CF761D Dasha and Very Difficult Problem

# 题目大意 现有a[i]，b[i]两个数组(l

第一行包含3个整数n,l,r 其中(1

一行符合条件的b数组， 若没有符合的情况，则输出'-1'(没有引号)

Sequence $ b $ which was found in the second sample is suitable, because calculated sequence $ c=[2-3,2-4,2-8,9-9]=[-1,-2,-6,0] $ (note that $ c_{i}=b_{i}-a_{i} $ ) has compressed sequence equals to $ p=[3,2,1,4] $ .
