2.某年级学生共选修6门课程，期末考试前，必须提前将这6门课程考完，每人每天只在下午至多考一门课程，设6门课程为C1，C2，C3，C4，C5，C6，S(Ci)为学习Ci的学生集合。已知S(Ci)∩S(C6)≠ф，i=1，2，...，5，S(Ci)∩S(Ci+1)≠ф，i=1，2，3，4，S(C5)∩S(C1)≠ф，问至少安排_____天才能考完这6门课程。四.阅读程序（阅读程序（共4题，每题8分，共计32分）1.programProgram1;

vara,b,c,d,sum:longint;

begin

read(a,b,c,d);

a:=amod23;b:=bmod28;c:=cmod33;

sum:=a*5544+b*14421+c*1228-d;

sum:=sum+21252;sum:=summod21252;if(sum=0)thensum:=21252;writeln(sum);end.输入：28310223320

2.programProgram2;

const

u:array[1..4]ofinteger=(0,5,3,1);v:array[1..4]ofinteger=(0,7,6,5);vara,b,c,d,e,f,x,y,z:integer;

begin

read(a,b,c,d,e,f);

z:=f+e+d+(c+3)div4;y:=5*d+u[cmod4];if(b>y)thenbegin

z:=z+(b-y+8)div9;

x:=((b-y+8)div9*9-(b-y))*4+11*e+v[cmod4];endelse

x:=(y-b)*4+11*e+v[cmod4];if(a>x)then

z:=z+(a-x+35)div36;writeln(z)end.

输入：479205647

3.programProgram3;varm,n:integer;mark:Boolean;
