Write a DECIMATOR function that takes a unit of character and minimizes it (i.e. removes the last 1/10 of characters). Always zoom in: if a bullet unit has 21 characters, 1/10 of the characters will be 2.1 characters, so DECIMATOR removes 3 characters. DECIMATOR is not kind! Examples decimator ("1234567890") 12 "123456789" # 10 characters, taken out 1. decimator ("1234567890AB") # 12 characters, 2 are released. "1234567890" decimator ("123") "12" # 3 characters, taken out 1. decimator ("123456789012345678901") # 21 characters, issued 3. Solve in Ruby "123456789012345678"
Write a function that takes in an array of integers and returns the integers that are either palindromes or almost-palindromes. An almost-palindrome is any integer that can be rearranged to form a palindrome. For example, the numbers 677 and 338 are both almost- palindromes, respectively. Examples since they can be rearranged to form 767 and 383, palindromeSieve([443, 12, 639, 121, 3232]) → [443, 121, 323 // Since 443 => 434; 121 is a palindrome; 3232 => 2332 or 3:
Python programme that calculates the eigenvalues and eigenvectors of a matrix using the numpy linalg package. As illustrated in the code below, it returns the eigenvalues and eigenvectors as one eigenvector per column of a matrix. The matrix A's eigenvalues are contained in the vector w, and the matrix V has one eigenvector per column. Eigenvalues for the given matrix A are 2, 1, and 4, and we can see that the determinant of A is equal to the product of these values and the trace of A is equal to the sum of these values.

All information for this problem is given right here. Google “magic square" and you'll see a magic square is a square (i.e., n x n) matrix of positive integers such that the sum of each row = sum of each column = sum of the top-right to bottom-left diagonal = sum of the bottom-left to top-right diagonal. I want you to start by placing this code in your main.cpp file: // Programmer: .. // Description: Determine if a square matrix is a magic square or not. const int NUM_ROWS_COLS = 3; // Number of rows/columns in the square matrix. // Prototype for function that accepts a two-dimensional matrix of integer // values and returns "true" if the values form a magic square and "false" if not. bool IsMagicsquare (int matrix[NUM_ROWS_COLS][NUM_ROWS_COLS]); #include using namespace std; int main() { int matrix[NUM_ROWS_COLS][NUM_ROWS_COLS] = { 8, 1, 6 }, { 3, 5, 7 }, { 4, 9, 2 } }; if ( IsMagicSquare(matrix) ) { cout « "Matrix is a magic square!" « endl; else cout « "Matrix is NOT a magic…

Create a program that accepts an integer N, and pass it to the function generatePattern. generatePattern() function which has the following description: Return type - void Parameter - integer n This function prints a right triangular pattern of letter 'T' based on the value of n. The top of the triangle starts with 1 and increments by one down on the next line until the integer n. For each row of in printing the right triangle, print "T" for n times. In the main function, call the generatePattern() function. Input 1. One line containing an integer Output Enter N: 4 T TT TTT TTTT
