WebApr 6, 2024 · The diag () function is used to extract and construct a diagonal 2-d array with a numpy library. It contains two parameters: an input array and k, which decides the diagonal, i.e., main diagonal, lowe diagonal, or the upper diagonal. It is the numpy library function, which is used to perform the mathematical and statistics operation on the ... WebFeb 17, 2024 · diag Function: You can use the diag function in Python to construct a diagonal matrix. It is contained in the NumPy library and uses two parameters. The diag function is numpy.diag (v, k=0) where v is an array that returns a diagonal matrix. Specifying v is important, but you can skip k. incantations on accupuncture needles
Find difference between sums of two diagonals
WebNote that reusing variables (like you are with j) is often a bad idea, as demonstrated here.Declare variables in the tightest possible scope; declaring a variable has no inherent cost.You can declare (and update) multiple variables in a for loop (provided they are of the same type), so for (int i = 0, j = 0; i WebMar 23, 2024 · In this HackerRank Diagonal Difference problem solution Given a square matrix, calculate the absolute difference between the sums of its diagonals. For example, the square matrix arr is shown below: 1 2 … WebJan 29, 2024 · The secondary diagonal is. Sum across the secondary diagonal: 4 + 5 + 10 = 19. Difference: 4 - 19 = 15. Now the last step is to find the difference between the sum of diagonals, so add the first diagonal and the second diagonal after that mod the difference so 4 - 19 = 15. Hence we got our solution. Note: x is the absolute value of x. inclund
