In Python, if we want to limit the large amount of data from displaying, we can use the reprlib module. To use this module, we should import it using. import reprlib There are different classes and methods related to reprlib. These are − Class reprlib.Repr The Repr class provides formatting services. It creates functions like built-in repr(). In this class we can add size limits and different object types. Method reprlib.repr(object) This method is used to return string like built-in repr() method, But in this case there is a limits on most sizes. Repr Objects The Repr object ... Read More
For developing GUI applications tkinter is very popular and easy. Using tkinter easily develop GUI games. Here also we are trying to develop color game. In this game the player has to enter color of the word that appears on the screen and hence the score increases by one, the total time to play this game is 30 seconds and colors used in this game are Red, Blue, Green, Pink, Black, Yellow, Orange, White, Purple and Brown. The interface will display name of different colors in different colors. User has to identify the color and enter the correct color name ... Read More
Stack is a subclass of Vector that implements a standard last-in, first-out stack. Stack only defines the default constructor, which creates an empty stack. Stack includes all the methods defined by Vector, and adds several of its own. Stack( ) Apart from the methods inherited from its parent class Vector, Stack defines the following methods − Sr.No. Method & Description 1 boolean empty() Tests if this stack is empty. Returns true if the stack is empty, and returns false if the stack contains elements. 2 Object peek( ) Returns the element ... Read More
In 8085 Instruction set, ACI is a mnemonic which stands for 'Add with Carry Immediate to Accumulator' and here “d8” stands for any 8-bit or 1-Bytedata. This instruction is actually meant for adding one 8-bit immediate data or operand to the Accumulator along with the carry value. The result of the addition will be stored in the Accumulator itself and replacing initial value of the Accumulator. As it is an arithmetic instruction, so the flags are affected based on the result. It holds 2-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ACI Data CE 2 ... Read More
For the secure hash and message digest process, we should use the hashlib module. This module implements a common interface for different secure hash algorithm like SHA1, SHA224, SHA256, SHA512 etc. Also the RSA’s MD5 algorithm. Older algorithms are known as the Message Digest and the new methods are called Secure Hash. To use this module, we need to import the hashlib module in the python code. import hashlib In this method, there are some predefined algorithms like md5, sha1, sha224, sha256, sha512 are present. We can add additional algorithms from the OpenSSL library. Some methods, constants of ... Read More
Given three number a b and c, our task is that we have to find the maximum element in among in given number. Example Input: a = 2, b = 4, c = 3 Output: 4 Algorithm Step 1: input three user input number. Step2: Add three numbers to list. Step 3: Using max() function to find the greatest number max(lst). Step 4: And finally we will print maximum number. Example Code def maximum(a, b, c): list = [a, b, c] return max(list) # ... Read More
A 2D array can be dynamically allocated in C using a single pointer. This means that a memory block of size row*column*dataTypeSize is allocated using malloc and pointer arithmetic can be used to access the matrix elements. A program that demonstrates this is given as follows. Example Live Demo #include #include int main() { int row = 2, col = 3; int *arr = (int *)malloc(row * col * sizeof(int)); int i, j; for (i = 0; i < row; i++) ... Read More
In 8085 Instruction, SUB is a mnemonic that stands for ‘SUBtract contents of R from Accumulator. Here R stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M Mnemonics, Operand Opcode(in HEX) Bytes SUB A 97 1 SUB B 90 1 SUB C 91 1 SUB D 92 1 SUB E 93 1 SUB H 94 1 SUB L 95 1 SUB M ... Read More
To start a task in C#, follow any of the below given ways. Use a delegate to start a task. Task t = new Task(delegate { PrintMessage(); }); t.Start(); Use Task Factory to start a task. Task.Factory.StartNew(() => {Console.WriteLine("Welcome!"); }); You can also use Lambda. Task t = new Task( () => PrintMessage() ); t.Start();
Given two user input matrix. Our task is to display the addition of two matrix. In these problem we use nested List comprehensive. Algorithm Step1: input two matrix. Step 2: nested for loops to iterate through each row and each column. Step 3: take one resultant matrix which is initially contains all 0. Then we multiply each row elements of first matrix with each elements of second matrix, then add all multiplied value. That is the value of resultant matrix. Example Code # Program to multiply two matrices A=[] n=int(input("Enter N for N x N matrix: ")) ... Read More
