Wie fusioniere ich zwei sortierte Arrays?

	 * This code merges two arrays, sorted in ascending

Zwei sortierte Arrays verschmelzen

public static int[] merge(int[] a, int[] b) {

    int[] answer = new int[a.length + b.length];
    int i = 0, j = 0, k = 0;

So fusionieren Sie zwei sortierte Arrays

// Merge sorted arrays using javascript

let arrrone = [0,3,4,31];
let arrayTwo = [4,6,30,31,33];
let j = 0;
let k = 0;
let mergedArray = [];

let length = arrrone.length + arrayTwo.length;

console.log(length)

for(let i = 0; i<= length - 1; i++){
  if(arrrone[j] < arrayTwo[k]){
    mergedArray.push(arrrone[j]);
    j++;
  }
  else if(arrrone[j] > arrayTwo[k]){
    mergedArray.push(arrayTwo[k]);
    k++;
  }
  else if(arrrone[j] == arrayTwo[k]){
    mergedArray.push(arrrone[j]);
    mergedArray.push(arrayTwo[k]);
    j++;
    k++;
  }
}

console.log(mergedArray)

Zusammenführen zwei sortierte Arrays

def mergeArrays(arr1, arr2, n1, n2):
    arr3 = [None] * (n1 + n2)
    i = 0
    j = 0
    k = 0
 
    while i < n1 and j < n2:
        if arr1[i] < arr2[j]:
            arr3[k] = arr1[i]
            k = k + 1
            i = i + 1
        else:
            arr3[k] = arr2[j]
            k = k + 1
            j = j + 1
 
    while i < n1:
        arr3[k] = arr1[i]
        k = k + 1
        i = i + 1
 
    while j < n2:
        arr3[k] = arr2[j]
        k = k + 1
        j = j + 1
