There are two arrays with individual values. Write a JavaScript program to compute the sum of each individual index value in the given array.Sample array: array1 = [1,0,2,3,4]; array2 = [3,5,6,7,8,13]; Expected Output: [4, 5, 8, 10, 12, 13]...
You want to add together many objects in an array. Solution There are two good ways to accomplish this in Ruby. Plain vanilla iteration is a simple way to approach the problem: collection = [1, 2, 3, 4, 5] sum = 0 collection.each {|i| sum += i} ...
let array1 = [| 1 2 3 |] The type of the array elements is inferred from the literals used and must be consistent. F# Copy // This is an array of 3 integers. let array1 = [| 1; 2; 3 |] // This is an array of a tuple of 3 integers. let array2 = [| 1, 2, 3...
tboulden I was looking for a later post but, since this one turned up, your more recent strategy using Thunks appears to be relevant for the sorted list of lists problem. =LET(THUNKλ,LAMBDA(x,LAMBDA(x)),EXPANDλ,LAMBDA(ϑ,LAMBDA(r,c,INDEX(INDEX(ϑ,r,1)(),c))),m,ROWS(List...

My guess is that this is a positive decision to avoid situations that could potentially give rise to an 'array of arrays'. That is fine if there are active plans to support such data structures natively (we can wait) but, if not, defaulting to a padded 2D array would be a ...
