NFhbar

Given a matrix with dimension m * n, write a function called diagonalSort() which sorts the matrix diagonally in ascending order from the top left to the bottom right. Return the sorted matrix.

const matrix = [
  [3,3,1,1],
  [2,2,1,2],
  [1,1,1,2]
]

NFhbar

Array Intersection, 🟢

---

Problem

Create a function FindIntersection(strArr) that reads an array of strings stored in strArr which will contain 2 elements: the first element will represent a list of comma-separated numbers sorted in ascending order, the second element will represent a second list of comma-separated numbers (also sorted). Your goal is to return a list containing the numbers that occur in elements of strArr in sorted order. If there is no intersection, return an empty array.

Constraints

None.

Examples

NFhbar

{
    "amt": 0,
    "aur": "T",
    "ba": {
        "street": "",
        "city": "",
        "state": "al",
        "country": "US",
        "zip": ""
    },

NFhbar

Given an array of non-negative integers representing terraces in an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining.

Examples

Example #1

Input: arr[] = [2, 0, 2]
Output: 2

NFhbar

Zeros to End of Array

Given an array of random numbers, write a function:

function pushZerosToEnd(array){
    return arrayWithZeros
}

NFhbar

Target Value

Given two arrays a and b and target value t, write a function that returns the two values from each array that add up to the target t.

Ex:

const a = [3, 5, 7, 8]
const b = [3, 5, 1, 9]
const t = 12
