Confused between 32 bit or 64 bit??
Know your system architecture(in ubuntu) :

someuser@somelaptop:~$ lscpu
Architecture: i686 #

Pseudo-polynomial Algorithms:

An algorithm whose worst case time complexity depends on numeric value of input (not number of inputs) is called Pseudo-polynomial algorithm.
For example, consider the problem of counting frequencies of all elements in an array of positive numbers. A pseudo-polynomial time solution for this is to first find the maximum value, then iterate from 1 to maximum value and for each value, find its frequency in array. This solution requires time according to maximum value in input array, therefore pseudo-polynomial. On the other hand, an algorithm whose time complexity is only based on number of elements in array (not value) is considered as polynomial time algorithm.

In Linux(ubuntu), date n time change not working??

1. Do it again... but after making the changes.. don't close the pop-up(date-time window).
2. Open Terminal (alt+ctrl+T).
3. run command:
sudo apt-get update
(update command to update current date-time)

Want to use system(ubuntu) as hotspot??
3 simple steps:
