About

In this task, you will write a "determinateValue" function that will determine the value of an element in a matrix. The matrix should be filled with a zigzag, example matrix 5x5:

  [
    [ 1,  2,  6,  7, 15],
    [ 3,  5,  8, 14, 16],
    [ 4,  9, 13, 17, 22],
    [10, 12, 18, 21, 23],
    [11, 19, 20, 24, 25]
  ]

In example above if x = 2, y = 1 and n = 5, result should be 9 ( matrix[2][1] = 9 )

The function "determinateValue" will be called to determine the value of each element in the matrix, it is passed three parameters:

• x - index of array position (vertical index).
• y - index of element position in array (horizontal index).
• n - Matrix size.

Simple "code golf" conditions:

• C# - 250 chars limit.
• JS - 150 chars limit.
• Python - 160 chars limit.

Note

• Matrices can be very large.
• Values must not go beyond the matrix (filling in the form of a big triangle will not work).

The direction of filling, for clarity.
