题目:
Tokitsukaze is one of the characters in the game "Kantai Collection". In this game, every character has a common attribute — health points, shortened to HP.
In general, different values of HP are grouped into 4 categories: Category Aif HP is in the form of (4n+1), that is, when divided by 4, the remainder is 1;Category Bif HP is in the form of (4n+3), that is, when divided by 4, the remainder is 3;Category Cif HP is in the form of (4n+2), that is, when divided by 4, the remainder is 2;Category Dif HP is in the form of 4n, that is, when divided by 4, the remainder is 0The above-mentioned n can be any integer.These 4categories ordered from highest to lowest as A>B>C>D, which means category A is the highest and category D is the lowest.While playing the game, players can increase the HP of the character. Now, Tokitsukaze wants you to increase her HP by at most 2(that is, either by 0, 1 or 2). How much should she increase her HP so that it has the highest possible category?InputThe only line contains a single integer x(30≤x≤100) — the value Tokitsukaze's HP currently.OutputPrint an integer a(0≤a≤2) and an uppercase letter b (b∈{A,B,C,D}), representing that the best way is to increase her HP by a, and then the category becomes bNote that the output characters are case-sensitive.ExamplesInput33Output0 AInput98Output1 BNoteFor the first example, the category of Tokitsukaze's HP is already A, so you don't need to enhance her ability.For the second example: If you don't increase her HP, its value is still 98, which equals to (4×24+2), and its category is C.If you increase her HP by 1, its value becomes 99, which equals to (4×24+3), and its category becomes B.If you increase her HP by 2, its value becomes 100, which equals to (4×25), and its category becomes D . Therefore, the best way is to increase her HP by 1so that the category of her HP becomes B.题意:Tokitsukaze是游戏“Kantai Collection”中的角色之一。在这个游戏中,每个角色都有一个共同的属性 - 健康点,缩短为HP。通常,不同的HP值分为4类:A类如果HP是(4n + 1)的形式,也就是说,当除以4时,余数为1;B类如果HP的形式为(4n + 3),即除以4,则余数为3;C类如果HP的形式为(4n + 2),即除以4,则余数为2;D类如果HP是4n的形式,也就是说,当除以4时,余数为0上述n可以是任何整数。这4个从A到B> C> D从最高到最低排序的类别,这意味着A类最高,D类最低。在玩游戏时,玩家可以增加角色的HP。现在,Tokitsukaze希望你将她的HP增加至多2(即0,1或2)。她应该增加多少HP以使其具有最高级别?输入唯一的行包含一个整数x(30≤x≤100) - 目前Tokitsukaze的HP值。产量打印一个整数a(0≤a≤2)和一个大写字母b(b∈{A,B,C,D}),表示最好的方法是将她的HP增加a,然后该类别变为b请注意,输出字符区分大小写。例子输入33产量0 A.输入98产量1 B注意对于第一个例子,Tokitsukaze的HP类别已经是A,所以你不需要增强她的能力。对于第二个例子: 如果你不增加她的HP,它的值仍然是98,等于(4×24 + 2),其类别是C.如果将HP增加1,则其值变为99,等于(4×24 + 3),其类别变为B.如果将HP增加2,则其值变为100,等于(4×25),其类别变为D.因此,最好的方法是将她的HP增加1这样她的HP类别就变成了B.
