Bammmmm's blog ByBammmmm,history,3 years ago, Given an arrayAAof lengthNNwith positive elementsa1,a2,...,aNa1,a2,...,aNand two numbersLLandRR. Divide the array into minimum number of sub-arrays such that each subarray have sum in the range[L,R][L,R]. ...
Explanation: Array can be divided into [1,2,3] , [2,3,4] , [3,4,5] and [9,10,11]. Example 3: Input: nums = [3,3,2,2,1,1], k = 3 Output: true Example 4: Input: nums = [1,2,3,4], k = 3 Output: false Explanation: Each array should be divided in subarrays o...
Given an array A of n real numbers, the maximum subarray problem is to find a contiguous subarray which has the largest sum. The k-maximum subarrays problem is to find ksuch subarrays with the...doi:10.1007/978-3-030-34029-2_29Ovidiu Daescu...
Given an integer array nums and an integer k, please return the k-th largest element in the array. Your algorithm’s runtime complexity must be in the order of \( O(n) \), prove the correctness and analyze the complexity.(k is much smaller than n, n is the length of the ...
215. Kth Largest Element in an Array Given an integer arraynumsand an integerk, returnthekthlargest element in the array. Note that it is thekthlargest element in the sorted order, not thekthdistinct element. Example 1: Input: nums = [3,2,1,5,6,4], k = 2 ...

* A is an array and p, q, and r are indices numbering elements of the array * such that p <= q < r. * * This procedure assumes that the subarrays A[p. .q] and A[q + 1. .r] are in * sorted order. It merges them to form a single sorted subarray that replaces ...

Divide the problem (instance) into subproblems. 2. Conquer the subproblems by solving them recursively. 3. Combine subproblem solutions. Example: merge sort 1. Divide: Trivial. 2. Conquer: Recursively sort 2 subarrays. 3. Combine: Linear-time merge. T(n) = 2 T(n/2) + O(n) # ...
Basically just brute-force the numbers gotten when you add 1 to every digit starting from 0. The numbers can't be stored because they get large very quickly. To fix this, store the count of each digit in the current number in an array instead and update the array to the next number ...
