How do I combine two arrays?

To merge elements from one array to another, we must first iterate(loop) through all the array elements. In the loop, we will retrieve each element from an array and insert(using the array push() method) to another array. Now, we can call the merge() function and pass two arrays as the arguments for merging.

How do I combine two arrays from another array?

In order to merge two arrays, we find its length and stored in fal and sal variable respectively. After that, we create a new integer array result which stores the sum of length of both arrays. Now, copy each elements of both arrays to the result array by using arraycopy() function.

What is merging of two arrays in C?

Take two arrays as input and try to merge or concatenate two arrays and store the result in third array. The logic to merge two arrays is given below − J=0,k=0 for(i=0;i<o;i++) {// merging two arrays if(a[j]<=b[k]){ c[i]=a[j]; j++; } else { c[i]=b[k]; k++; } }

Can Mergesort be done in place?

The standard implementation of merge sort is not in-place; but we can make it in-place by modifying the way we merge the lists. However, this will affect the run-time complexity of the algorithm. So basically, standard merge sort with a modified method to merge the lists in-place is called in-place merge sort.


We have an array of size m+n in which m elements are present, in sorted order, and a second array of size n, again in sorted order. We want both of them to be sorted and present in the first array. No third array is supposed to be given.

Example:

   1, 3, 55, 66, 77, _, _, _ 
   5, 9, 20 

The answer would be:

   1, 3, 5, 9, 20, 55, 66, 77
