Merge two sorted arrays recursively

Web13 apr. 2024 · The merge sort array in java is a divide-and-conquer method of sorting an array. The two arrays are split into sub-arrays, and then these sub-arrays are merged back together in a sorted order. The key difference is that the two arrays being merged are already sorted, which means that the merge process can be done in a more efficient … Web25 jul. 2024 · I am trying to merge two sorted arrays recursively, and I can merge the first few numbers until one pointer exits the array.
