An efficient approach will be to observe first that there can be a total of 26 unique characters only. The slow random-access performance of a linked list makes some other algorithms (such as quicksort) perform poorly, and others (such as heapsort) completely impossible. In this algorithm, the array is initially divided into two equal halves and then they are combined in a sorted manner. It can limit the efficiency of the algorithm in certain. Step 3: Now, merge the unit array to form sorted subarrays and continue getting bigger subarrays. While merging the branches it is possible that some merge conflicts will be raised then git will prompt you to resolve the merge conflicts. Another Simple Solution is first Merge both lists, then reverse the merged list. Merge sort uses additional storage for sorting the auxiliary array. Merge sort is often preferred for sorting a linked list. Step 1: If it is only one element in the list, consider it already. Inserting elements into the buckets: Take each element from the input array. In QuickSort, ideal situation is when median is always chosen as pivot as this results in minimum time.
