You are given a sequence of numbers, ARR
. Your task is to return a sorted sequence of ARR
in non-descending order using the Merge Sort algorithm.
The Merge Sort...
Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Divide the input array into two halves recursively until each array has only one element.
Merge the sorted halves to produce a completely sorted array.
Time complexity of Merge Sort is O(n log n).
Given a rotated sorted array ARR
of size 'N' and an integer 'K', determine the index at which 'K' is present in the array.
1. If 'K' is not present...
Given a rotated sorted array, find the index of a given integer 'K'.
Use binary search to efficiently find the index of 'K'.
Consider the rotation of the array while performing the search.
Handle cases where 'K' is not present in the array by returning -1.
