Zip It

Write a function called zipIt that accepts two already sorted arrays and returns a new array which contains all the elements present in both the arrays in a sorted order.

• Note: Do not use a sorting algorithm

Eg.

zipIt([1,5,9,10], [2,4,7])

function boxesRows(boxes) {
  let result = [];
  while (1) {
    let count = 0;
    let zeroBoxCount = 0;
    for (let i = 0; i < boxes.length; i++) {
      if (boxes[i] > 0) {
        boxes[i]--;
        count++;
      } else {

function boxesRows(boxes){
 let result=[];
 let max=0;
 // find the maximum number
 for(let i=0;i<boxes.length;i++){
     if(boxes[i]>max){
         max=boxes[i];
     }
 }
 // push zeros in the result array equal to the max number

There is an array of boxes where each element of an array represents the number of boxes stacked on top of each other in that column. For eg. boxes=[4,1,2,3,2,1].

This is a row of boxes where the first column of boxes has 4 boxes stacked on top of each other. The second column has 1 box, the third column has 2 boxes stacked on top of each other and the fourth column has 3 boxes stacked on top of each other and so on. So the boxes look like this:

              B
              B     B
 B B B B

Write a function that sorts a given array using the Bubble Sort Algorithm and returns the sorted Array. For eg.

bubbleSort([1,5,3,0])

should return [0,1,3,5]

bubbleSort([-1,0,-5,5,8])

should return [-5,-1,0,5,8]

Bubble Sort Algorithm

• Please watch the following video to understand the Bubble Sort Algorithm

Stepwise Implementation of the Bubble Sort Algorithm

If the input is [6,2,9,5,1,3] the steps are:

compare 6 and 2 - swap
compare 6 and 9 - no change

Practice Challenge #6

Anagram Part 2

This challenge is an extension of the previous Anagram challenge which was done on Day 3.(Link to Previous Challenge).

Using the .sort() method and .indexOf() method to solve this problem is not very efficient(Why?). We shall now redo the problem using a more efficient method of creating Objects.

Problem Statement

• Write a function that accepts two strings and checks whether the first string is an anagram of the second string. If yes, the function returns true , else it returns false. The case(upper/lower)of the character MATTERS.
• You need to create an Object for each of the strings and then compare the two Objects for equality.
• The keys of the Object will be the characters in the string and the value will be the frequency of the character.
