把1,2,3,4......按如下规律排列（第一行特殊),例如数字３在第一行Ｃ列,那么，数字2013在第几行几列.....具体如下图
解题如下
function main(args) {
lie = ""; //列
hang = 0; //行
num = 2013;
fournum = parseInt(num / 4); //包含多少个
mnum = num % 4; //目标数模4
hang = fournum;
if (mnum > 0) {
hang = hang + 1;
}
jo = hang % 2; //余数等于1是奇数
if (mnum == 3) {
lie = "C";
} else if (jo == 1) { //奇数
if (mnum == 0) {
lie = "D";
} else if (mnum == 1) {
lie = "E";
} else if (mnum == 2) {
lie = "B";
}
} else if (jo == 0) { //
if (mnum == 0) {
lie = "B";
} else if (mnum == 2) {
lie = "D";
} else if (mnum == 1) {
lie = "A";
}
}
// hang = hang-1;
console.log(num + "在第" + hang + "行,第" + lie + "列")
}
main()
