Python program to find Largest, Smallest, Second Largest, and Second Smallest in a List?
Array is given, we have to find out maximum, minimum, secondlargest, second smallest number.AlgorithmStep 1: input list element Step 2: we take a number and compare it with all other number present in the list. Step 3: get maximum, minimum, secondlargest, second smallest number.Example code# To find largest, smallest, second largest and second smallest in a List def maxmin(A): maxi = A[0] secondsmax = A[0] mini = A[0] secondmini = A[0] for item in A: if item > maxi: maxi ...
Read MorePython code to print common characters of two Strings in alphabetical order
Two user input strings are given, our task is to print all the common characters in alphabetical order.ExampleInput: string1: python string2: program Output: opExplanationThe letters that are common between the two strings are o (1 times), p (1 time)AlgorithmStep 1: first we take two input string. Step 2: next we will do to convert these two strings into counter dictionary. Step 3: Now find common elements between two strings using intersection ( ) property. Step 4: Resultant will also be a counter dictionary having common elements as keys and their common frequencies as value. Step 5: Use elements () method ...

Read MoreExtracting MAC address using C#
A MAC address of a device is a media access control address. It is a unique identifier assigned to a network.The MAC address technology is used by many technologies such as Ethernet, Bluetooth, Fibre Channel, etc.Here, we will use the following method to check for all the network interfaces on the computer.NetworkInterface.GetAllNetworkInterfacesFor this, the NetworkInterfaceType Enumeration is also used to specify the type of network interfaces.string addr = ""; foreach (NetworkInterface n in NetworkInterface.GetAllNetworkInterfaces()) { if (n.OperationalStatus == OperationalStatus.Up) { addr += n.GetPhysicalAddress().ToString(); break; } } return addr;Above, we have used the ...
Read MoreHow do I sort a two-dimensional array in C#
To sort a two-dimensional array in C#, in a nested for loop, add another for loop to check the following condition.Examplefor (int k = 0; k < j; k++) { if (arr[i, k] > arr[i, k + 1]) { int myTemp = arr[i, k]; arr[i, k] = arr[i, k + 1]; arr[i, k + 1] = myTemp; } }Till the outer loop loops through, use the GetLength() method as shown below. This is done to sort the array.Examplefor (int i = 0; i < arr.GetLength(0); i++) { for ...
Read MoreHow to use the GetType method of array class in C#?
The GetType() method of array class in C# gets the Type of the current instance (Inherited from Object).To get the type.Type tp = value.GetType();In the below example, we are checking the int value using the type.if (tp.Equals(typeof(int))) Console.WriteLine("{0} is an integer data type.", value)The following is the usage of GetType() method in C#.Exampleusing System public class Program { public static void Main() { object[] values = { (int) 100, (long) 17111}; foreach (var value in values) { Type tp = value.GetType(); if (tp.Equals(typeof(int))) ...
Read MoreHow to create custom attributes in C#?
Custom attributes that can be used to store declarative information and can be retrieved at run-time.Let us see how to declare custom attribute.[AttributeUsage ( AttributeTargets.Class | AttributeTargets.Constructor | AttributeTargets.Field | AttributeTargets.Method | AttributeTargets.Property, AllowMultiple = true)] public class DeBugInfo : System.AttributeFor our example, let us construct a custom attribute named DeBugInfo, which stores the information obtained by debugging any program.The DeBugInfo class has three private properties for storing the first three information and a public property for storing the message. Hence the bug number, developer's name, and date of review are the positional parameters of the DeBugInfo class and the ...
Read MoreConst vs Static vs Readonly in C#
ConstConstant fields are the fields that cannot be modified. At the time of declaration, you need to assign a value to it.const int a = 5;StaticIf the static modifier is applied to a class then you cannot instantiate the class using the new keyword. You can use the static keyword on methods, properties, classes, constructors, etc.static int a = 10;ReadonlyA Readonly field is initialized at the time of declaration or you can also set it within the constructor.Let us see an example in which the readonly field is initialized inside the constructor.Exampleclass Demo { readonly int a; public ...
Read MoreDifference between IComparable and IComparer Interface in C#
IComparable Interface in C#Use the IComparable Interface in C# to sort elements. It is also used to compare the current instance with another object of same type.It provides you with a method of comparing two objects of a particular type. Remember, while implementing the IComparable interface, CompareTo() method should also be implemented.Let us see an example −int IComparable.CompareTo(object ob) { Vehicle v=(Vehicle)ob; return String.Compare(this.make, v.make); }IComparer interface in C#The IComparer interface is used to sort elements that compare two objects and provides additional comparison method.Exampleprivate class sortYearAscendingHelper : IComparer { int IComparer.Compare(object ob1, object ob2) { ...
Read MoreHow can we update any value in MySQL view as we can update the values in MySQL table?
As we know that with the help of UPDATE statement we can update the values in MySQL table and in the similar way we can update the values in MySQL views. The syntax of UPDATE statement would be the same except at the place of table name we have to provide the name of the view. We are taking the data as follows from a view named ‘Info’ to illustrate the above concept −mysql> Select * from Info; +------+---------+------------+ | Id | Name | Subject | +------+---------+------------+ | 101 | YashPal ...
