Interview Enterprise Shell programming basic problem Solving practice (pro-Test)

The problem is to choose the old boy teacher blog inside of the problem, extrapolate of which also extended two questions.

Anyway

1. Use the shell or Python to write a square that receives the number entered by the user.

Method: Vim zhong1.sh

#!/bin/bashread-p "Please Enter a number:" N for ((x=1;x<= $n; x + +));d O for ((y=1;y<= $n *2;y++)) do Echo-n " + "do echo" "Done"

Example 2: implementation by number (zhong2.sh)

Method: Vim zhong2.sh

#!/bin/bashread-p "Please Enter a number:" N for ((x=1;x<= $n; x + +));d O for ((y=1;y<= $n; y++)) do Echo-n " "Done Echoes" "done

  2. Use the shell or Python to write a isosceles triangle that receives the number entered by the user.

For example: implemented with the * number (zhong3.sh)

Method: Vim zhong3.sh

#!/bin/bashread-p "Please Enter a number:" N for ((x=1;x<= $n; x + +));d O for ((z=1;z<= $n-x;z++));d o echo-n "" Done for ((y=1;y<=a+1;y++));d o echo-n "*" Did Echo a=$ ((a+2)) done

3 . Please write an inverted isosceles triangle with the shell or Python to receive the user input numbers. (continuation of the second question)

For example: implemented with the * number (zhong33.sh)

650) this.width=650; "Src=" Http://s3.51cto.com/wyfs02/M00/84/4D/wKiom1eMbpmALiJfAAAfJ3xdErw315.jpg-wh_500x0-wm_3 -wmp_4-s_1089656928.jpg "style=" Float:none; "title=" psb4.jpg "alt=" Wkiom1embpmalijfaaafj3xderw315.jpg-wh_50 "/>

Method: Vim zhong33.sh (can be changed on the basis of zhong3.sh)

#!/bin/bashread-p "Please Enter a number:" N for ((x=1;x<= $n; x + +));d O for ((z=0;z<x-1;z++));d o echo-n "" Done for ((y=1;y<= $n-(a+1-$n); y++);d o echo-n "*" Do Echo a=$ ((a+2)) done

4 . Please write a diamond in shell or Python to receive the user input. (continuation of the second question)

For example: implemented with the * number (zhong333.sh)

650) this.width=650; "Src=" Http://s3.51cto.com/wyfs02/M00/84/4D/wKioL1eMbpmAz3j8AAA2tkJ28Po115.jpg-wh_500x0-wm_3 -wmp_4-s_3298491014.jpg "style=" Float:none; "title=" psb5.jpg "alt=" Wkiol1embpmaz3j8aaa2tkj28po115.jpg-wh_50 "/>

method: Vim zhong333.sh

 #!/bin/bashread -p  "Please enter a number : " n for  ((x=1;x<= $n; x + +);d o     for  ((z=1;z<= $n-x;z++)); do    echo -n  " "     done    for   ((y=1;y<=a+1;y++));d o    echo -n  "*"     done     echo     a=$ ((a+2)) doneb=2for  ((x=1;x<= $n; x + +));d o     for  ((z=0;z<=x-1;z++));d o      echo -n  "       done    for  ((y=1;y<= $n-(b+1-$n); y++);d o       echo -n  "*"     done    echo     b=$ ((b+2)) Done 

5. Use shell or Python to write a right-angled trapezoid program that receives user input parameters N,m

For example: implemented with the * number (zhong4.sh)

650) this.width=650; "Src=" Http://s3.51cto.com/wyfs02/M02/84/4D/wKiom1eMbpnhI7MjAABUVcuEo4E559.jpg-wh_500x0-wm_3 -wmp_4-s_2815179913.jpg "style=" Float:none; "title=" psb6.jpg "alt=" Wkiom1embpnhi7mjaabuvcueo4e559.jpg-wh_50 "/>

Method: Vim zhong4.sh

#!/bin/bashfor ((x=1;x<=$2;x++));d O for ((y=1;y<=$1+a;y++)) does echo-n "+" Done a=$ ((a+1)) echo " "Done

The above results are pro-measured, can fully achieve the requirements of the topic
