I want to call a function to generate row an column pair as string to fill a table cell with at least 1 cell gap between theme like this. as you see in image there is 1 empty cell between filled cells. a have an array like this to fill table cells: arr=[‘1,1′,’4,2’] //which means ..

so i have an assigment to do and i’m stuck, i just start learning about matrix and the multidimensional array and i would like to know what i did wrong. this the assigmen: A symmetric matrix is a matrix that passes this boolean condition: mat[i][j] === mat[j][i] Write the function checkIfSymmetric(mat). this what i did: ..

I have a system of resistors, something like this: Resistor schematic I made a website which renders diagrams like this one (not this one exactly). The user can change resistance of each resistor. I want to calculate every current in the system. I found a solution using Kirchhoff’s laws, which gave me a system of ..

I have a 2d matrix of arrays: let matrix = [ [a, b, c], [d, e, f], [g, h, i] ]. How can i print on the console any array on new line and without commas between elements? Like this: a b c d e f g h i console.log(matrix.join(‘n’)) prints any array on new ..

What is the best way to sort nodes for a directed graph? I already made an algorithm with an array A of arrays B, where the elements of array A represent the column and the position of the elements in array B represent the rows. Then the nodes are placed in a grid depending of ..

I want to render a table on the screen. So, I create a two-dimensional array and iterate over it in the render function: class Matrix<T> extends Array<T[]> { constructor(width: number, height: number, initialValue?: T) { super(height); this.fill(new Array(width).fill(initialValue); } } let matrix = new Matrix(3, 3, 0) // I wan’t the central cell to have ..
