求大佬帮助写一个算法

    例如sequence是                     1,2,3,4,5,6,7
    则对应的std_row_n是             6,4,2,0,1,3,5
    例如sequence是                     1,2,3,4,5,6,7,8
    则对应std_row_n是                 8,6,4,2,1,3,5,7

compare (a , b ){
c = a ;
d = b ;
if (a %2 ==0 ){ c = -a;}
if(b%2 ==0) {d = -b ;}
return a > b ;
}
