program Noname0; ：程序名
const n=7; ；定义常量 n代表7
var a:array[1..n] of integer; ；定义变量 a为整数数组[1..n]
i,j,k,t:integer; ；i,j,k,t为整数型变量
begin ；程序起始处
write('ggg'); ：输出 ggg
for i:=1 to n do read(a[i]); ；for循环,依次读入 a[i]到a[n]
for i:=1 to n-1 do ；for循环 i每次加1,从1加到n-1
for j:=n downto i+1 do ；for循环 j每次减1,从n减到i+1
if a[j-1]
