请您仔细阅读下的代码,修改其代码,将程序结果修改为,如果输入1,就显示“星期一”,以些类推,一直到输入“7”,显示星期日。 #!/bin/bash printf "Input integer number: " read num if ((num==1)); then echo "Monday" elif ((num==2)); then echo "Tuesday" elif ((num==3)); then echo "Wednesday" elif ((num==4)); then echo "Thursday" elif ((num==5)); then echo "Friday" elif ((num==6)); then echo "Saturday" elif ((num==7)); then echo "Sunday" else echo "error" fi
