Read MorePsensor graphical hardware temperature monitor for linux
Generally speaking, Linux administrators are supposed to track the performance of your computer hardware issues or faults which might occur accidentally. Sometimes, overheating issues can occur due to various software concerns such as buggy graphics card driver, mis-configured fan control program, malfunctioning CPU frequency scaling daemon, etc. If these problems are not detected early, these might become serious threats which may cause permanent damage on your hardware. Hence, keeping an eye on over heating issues should be your top priority.Psensor is considered to be one of the simplest application to monitor hardware temperature and to plot real-time analytics from raw ...
Read MoreC Program to check if the points are parallel to X axis or Y axis
Given n number of points we have to check that whether the point is parallel to x-axis or y-axis or no axis according to a graph. A graph is a figure which is used to show a relationship between two variables each measured along with axis at right angles. Parallel are the same lines which are having same distance at all points, like railway tracks are parallel to each other.So, we have to find whether the points are parallel to x-axis or y-axis means the distance between the coordinates and the axis are same at all points.What is an axisThe ...

Read MoreCheck if a number is formed by Concatenation of 1, 14 or 144 only in C++
Here we will see one problem, that can tell that whether a string or a number is a concatenation of 1, 14 or 144 only. Suppose a string is “111411441”, this is valid, but “144414” is not valid.The task is simple, we have to fetch a single digit, double-digit and triple-digit number from the last, and check whether they match with any of these three (1, 14 and 144), if we get one match, divide the number with it, and repeat this process until the entire number is not exhausted.Example#include #include using namespace std; bool checkNumber(long long number) ...
Read MoreCheck if a number can be expressed as sum two abundant numbers in C++
Suppose we have a number. We have to express this as sum of two Abundant number, if yes, print the numbers, otherwise print -1. A number is said to be Abundant number is sum of all proper divisor of the number, denoted by sum(n) is greater than the value of number.To solve this, we will store all abundant numbers into a set, and for given number n, run a loop for i = 1 to n, and check n and (n – i) are abundant or not.Example#include #include #define N 100005 using namespace std; set getAbundantSet() { ...
Read MoreCheck if a given string is a rotation of a palindrome in C++
Here we will see, one string is palindrome after certain rotation or not. A palindrome is a string that is the same in both directions. A string rotation is a palindrome if that is like AAAAD. this is not a palindrome directly, but its rotation AADAA is a palindrome.To check a string is rotated palindrome or not, then we will check this is a palindrome or not at the first time, after that, rotate it by one character, then check again, this checking will be performed n amount of time, where n is the number of characters.Example#include #include ...
Read MoreCheck if a circle lies inside another circle or not in C++
Suppose we have two circles (center points, and the radius values), we have to check one circle is fit inside another circle or not. There are three possible causes.The smaller circle lies completely inside the bigger one, without touching each other. In this case, the sum of the distance between the centers, and the smaller radius, is lesser than a bigger radius. So the smaller one will be inside the bigger one.The second case is the smaller circle is inside the bigger ones, but also touches the circumference of the bigger circle.The third case is, some part of the smaller ...
