How to generate random numbers with no repeats?
To generate a range of random numbers with no repeats, you can use this formula: n is the number of cells to fill. To avoid manual calculations, you can supply it as (no. of rows * no. of columns). For example, to fill 10 rows and 5 columns, use 50^2 or (10*5)^2.
How to find the two non repeating elements in an array?
Given an array in which all numbers except two are repeated once. (i.e. we have 2n+2 numbers and n numbers are occurring twice and remaining two have occurred once).

How to create random array of numbers in JavaScript?

For example, to get a list of 1,000 unique numbers as the final result, RANDARRAY would have to generate of array of 1,000,000 random numbers (1000^2) internally. In such situations, instead of raising to power, you can multiply n by, say, 10 or 20.
