Maximum equilibrium sum in an array After this for each index check if presum [i] is equal to suffsum [i] and if they are equal then compare their value with the overall maximum so far. This video explains how to find equilibrium point in an array. Apr 14, 2023 · The equilibrium sum of the given array is the sum at a particular point or index of the array after which the subarray has the total sum equal to the sum of the subarray starting from the 0th index to the current index (including the current index). Feb 28, 2025 · Do another traversal of the array and store suffix sum in another array suffsum [], in which suffsum [i] stores sum of subarray arr [i. Can you solve this real interview question? Find Pivot Index - Given an array of integers nums, calculate the pivot index of this array. In this example, the maximum equilibrium sum occurs when the array is divided into two parts: [1, 2, 3, 4] and [5, 6].

See full list on tutorialspoint. Jan 31, 2022 · Do another traversal of the array and store suffix sum in another array suffsum [], in which suffsum [i] stores sum of subarray arr [i. Aug 28, 2024 · After iterating through the array, the function returns the max_sum, which represents the maximum equilibrium sum found. Find the maximum value of prefix sum which is also suffix sum forRecommended: Please try your approach on {IDE} first, before moving on to the solution. If the index is on the left edge of the array, then the left sum is 0 because there are no Jul 23, 2025 · Do another traversal of the array and store suffix sum in another array suffsum [], in which suffsum [i] stores sum of subarray arr [i. An example usage is provided using the array arr = [1, 5, 3, 8, 2, 7]. An equilibrium index in an array is an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes. We will see the examples and the code implementations in JavaScrript with the different approaches. You have to find the maximum sum of a pair of numbers from nums such that the largest digit in both numbers is equal. For example, 2373 is made up of three distinct digits: 2, 3, and 7, where 7 is the largest among them. Given an array arr[].

For instance, consider the array A = [-7, 1, 5, 2, -4, 3, 0]. Return the maximum sum or -1 if no such pair exists. To find the maximum equilibrium sum in an array, we need to understand what the equilibrium sum means. 11M subscribers Subscribed Write a program to find the equilibrium index of an array. Note: This is an excellent coding question to learn time and space complexity optimization using a prefix array and a single loop using variables. Jul 23, 2025 · Do another traversal of the array and store suffix sum in another array suffsum [], in which suffsum [i] stores sum of subarray arr [i. The method 'getMaxEquilibriumSumOptimized' computes the total sum of the array, then iterates through it to find the maximum sum where the left and right sums are equal. The sum of both parts is 9, which is the maximum equilibrium sum in the array. An array's equilibrium index is an index such that the sum of elements at lower indexes equals the sum of elements at higher indexes. The pivot index is the index where the sum of all the numbers strictly to the left of the index is equal to the sum of all the numbers strictly to the index's right. 2 methods are explained which involves a preprocessing efficient method which works in just O Equilibrium index of an array | GeeksforGeeks GeeksforGeeks 1.
