1// https://www.geeksforgeeks.org/timsort/2/*3TimSort is a sorting algorithm based on Insertion Sort and Merge Sort.4A stable sorting algorithm works in O(n Log n) time5Used in Java’s Arrays.sort() as well as Python’s sorted() and sort().6First sort small pieces using Insertion Sort, then merges the pieces using 7 merge of merge sort.8We divide the Array into blocks known as Run. 9We sort those runs using insertion sort one by one and then merge those runs 10 using combine function used in merge sort. 11If the size of Array is less than run, then Array get sorted just by using 12 Insertion Sort. 13The size of run may vary from 32 to 64 depending upon the size of the array. 14Note that merge function performs well when sizes subarrays are powers of 2. 15The idea is based on the fact that insertion sort performs well for small arrays.16Recommended: Please try your approach on {IDE} first, before moving on to the solution.17Details of below implementation:18We consider size of run as 32.19We one by one sort pieces of size equal to run20After sorting individual pieces, we merge them one by one. 21We double the size of merged subarrays after every iteration.22*/23// time complexity: Best O(n) | Avg O(n log(n)) | Worst O(n log(n))24// space complexity: O(n)25// Python3 program to perform TimSort. 26RUN = 32 27 28// This function sorts array from left index to 29// to right index which is of size atmost RUN 30insertionSort = (originalArray) => {31 // get array length32 let arrayLength = originalArray.length;33 let currentPosition, currentItem;34 console.log(`original array: ${originalArray}`)35 // loop from 1 since first element is sorted through end of array36 for (let index = 1; index < arrayLength; index++) {37 // set current item as value in array[index]38 currentItem = originalArray[index]39 // set current position as current index40 currentPosition = index41 // while current position is at least 1 and previous item's value is larger 42 // than current item43 while (currentPosition > 0 && originalArray[currentPosition - 1] > currentItem) {44 // set value at current position as previous position45 originalArray[currentPosition] = originalArray[currentPosition -1]46 // set current position as previous position47 currentPosition = currentPosition - 148 }49 // set value of current position as current item50 originalArray[currentPosition] = currentItem51 }52 return originalArray53}54 55// merge function merges the sorted runs 56merge = (originalArray, l, m, r) => {57 58 // original array is broken in two parts 59 // left and right array 60 let len1 = m - l + 161 let len2 = r - m 62 let left = []63 let right = []64 for (let x = 0; x < len1; x++) left.append(originalArray[l + x]) 65 // for (i in range(0, len1)) left.append(originalArray[l + i]) 66 for (let x = 0; x < len2; x++) right.append(originalArray[m + 1 + x]) 67 // for (i in range(0, len2)) right.append(originalArray[m + 1 + i]) 68 69 let i = 070 let j = 071 let k = l 72 // after comparing, we merge those two array 73 // in larger sub array 74 while (i < len1 && j < len2) { 75 76 if (left[i] <= right[j]) {77 originalArray[k] = left[i] 78 i += 1 79 }80 else {81 originalArray[k] = right[j] 82 j += 1 83 }84 k += 185 }86 // copy remaining elements of left, if any 87 while (i < len1) {88 originalArray[k] = left[i] 89 k += 1 90 i += 191 }92 // copy remaining element of right, if any 93 while (j < len2) {94 originalArray[k] = right[j] 95 k += 196 j += 197 }98}99// iterative Timsort function to sort the 100// array[0...n-1] (similar to merge sort) 101timSort = (originalArray, n) => {102 103 // Sort individual subarrays of size RUN 104 for (i in range(0, n, RUN)) insertionSort(originalArray, i, Math.min((i+31), (n-1))) 105 106 // start merging from size RUN (or 32).
