Private networks provide you highest speed that you require, ... Read More
Create 2 different arrays leftDis and rightDis. The leftDis will store the value when moved from left direction. The rightDis will store the shortest value when moved from right. Whenever the character is met add the position of the character to the array. In the last step calculate the minimum of both the arrays.Time Complexity − O(n)Space Complexity − O(n)Examplepublic class Arrays{ public int[] ShortestDistanceToCharacter(string s, char c){ int stringLength = s.Length; int[] leftDis = new int[s.Length]; int[] rightDis = new int[s.Length]; leftDis = Enumerable.Range(0, s.Length).Select(n => ...

As people are getting more awareness about the Internet these days, little, they know how to use it more securely and what are all the risks they are taking on every suspicious click they make. Many times, paid applications are available freely on some third-party app store, and people often try to download those applications from there, but those come with a lot of risks that you might be unaware of.Third-party App Stores offer cyberattackers an avenue through which they deliver their infected malicious apps to users unaware of these risks. Hence, it is always advised that before you download ... Read More
Most of the time, when we suddenly see a pop-up demanding an update, we tend to select the option of scheduling them later. In this article, we will see why those software updates are important, and what if we don't keep our system and its apps up-to-date?Realizing that you were hacked because you ignored the update pop-up on your system while you were working would be very hard to digest. Updating all the software, specifically the anti-virus and anti-malware programs, minimizes the chances of any loopholes in the program's security, ensuring that viruses, malware, and remote "hackers" stay out of ...

The easy approach is that we could create three nested loops and check one by one that the sum of all the three elements is zero or not. If the sum of the three elements is zero then print elements.Time Complexity − O(n3)Space Complexity − O(1)We could use an unordered set data structure to store each value of the array. Set provides the benefit of searching an element in O(1) time. So, for each pair in the array, we will look for the negative of their sum that might exist in the set. If such an element is found then ... Read More

One of the studies held at the Stanford University found that, yes, Android phones can be tracked even when their GPS and WiFi are not enabled by analyzing their power-use over time. It works on a simple rule that “A cellphone uses more power, the more away it is from the cell tower and the more obstacles are on its way to reach for a signal.” Along with this, all the other activities which use power can be factored out with the help of the algorithm the researchers studied.The term which they used to track you through your power consumption ...

CSRSS.exe stands for client-server runtime subsystem executable file, which is one of the legitimate windows OS processes that handles most of the graphical instruction sets of the windows OS. But as it is a widespread and known process, many attackers take advantage of this and release their infected malicious Trojan program under the disguise of CSRSS.exe name.How Does CSRSS.exe Trojan Spread?Before knowing how to remove CSRSS.exe, it’s obvious that we should understand how it could enter the system and how you can detect it?The main possibilities from where it could have entered your system are −Sometimes, while downloading other things, ...
