Day 86 Question: Given a linked list, sort the list using insertion sort. More details in the below link: http://bit.ly/q_86 Difficulty: Medium Like our FB Page: http://bit.ly/fb_page_pdt Join our FB Group to discuss about the solution: http://bit.ly/fb_group_pdt ============================= Linux command for the day: ============================= Linux sudo Usage: “sudo” stands for “super user do”. This command is used to execute the commands that can only be executed by super user or root. The users with root access can be found at “/etc/sudoers” file. Options: -V Display the version -l Display the commands that can be executed as a “sudo” user. -h Display help text -b Run the given command in background. Example: To install any package in centos you need to use “yum install” command. But normal user cannot run this command. Hence use “sudo yum install gvim” to install as a super user. It might prompt you to enter the password.
