Lesha plays the recently published new version of the legendary game hacknet. In this version character skill mechanism was introduced. Now, each player character has exactly n skills. Each skill is represented by a non-negative integer ai — the current skill level. All skills have the same maximum level A.ide
Along with the skills, global ranking of all players was added. Players are ranked according to the so-called Force. The Force of a player is the sum of the following values:学习
Now Lesha has m hacknetian currency units, which he is willing to spend. Each currency unit can increase the current level of any skill by 1 (if it's not equal to A yet). Help him spend his money in order to achieve the maximum possible value of the Force.this
The first line of the input contains five space-separated integers n, A, cf, cm and m (1 ≤ n ≤ 100 000, 1 ≤ A ≤ 109, 0 ≤ cf, cm ≤ 1000, 0 ≤ m ≤ 1015).spa
The second line contains exactly n integers ai (0 ≤ ai ≤ A), separated by spaces, — the current levels of skills.code
On the first line print the maximum value of the Force that the character can achieve using no more than m currency units.blog
On the second line print n integers a'i (ai ≤ a'i ≤ A), skill levels which one must achieve in order to reach the specified value of the Force, while using no more than m currency units. Numbers should be separated by spaces.排序

In the first test the optimal strategy is to increase the second skill to its maximum, and increase the two others by 1.ip
In the second test one should increase all skills to maximum.ci
简单题意input
你有n个技能能够学,你有m个技能点能够分配,每一个技能的上限值都是A,每一个技能都给出了至少要学的等级,而后你要合理分配技能点,使得战力最大
战力=满级技能*Cf+最小等级*Cm
而后咱们枚举满级的技能个数,显然咱们应该把那些至少学习等级大的点成满级,而后剩下的技能尽可能最小等级最大
因此咱们一开始从小到大排序,枚举后面i个变成满级,前面的二分最小等级,用前缀和判断可行性,而后计算出战力,更新答案
