Jan 14, 2022 · Equilibrium index of an array is an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes. For example, in an array A: Example : Input: A[] = {-7, 1, 5, 2, -4, 3, 0} Output: 3 3 is an equilibrium index, because: A[0] + A[1] + A[2] = A[4] + A[5] + A[6] Input: A[] = {1, 2, 3} Output: -1

Jan 15, 2025 · Given an array arr[] of size n, the task is to return an equilibrium index (if any) or-1 if no equilibrium index exists. The equilibrium index of an array is an index such that the sum of all elements at lower indexes equals the sum of all elements at higher indexes.

Feb 4, 2024 · In this article, we designed and implemented an algorithm to find all the equilibrium indexes of a Java array. The data structure doesn’t have to be an array. It could also be a List or any ordered sequence of integers.

In this section, we will learn what is equilibrium index in an array and how to find the equilibrium index through a Java program. Let's find the equilibrium index. According to the definition: We observe that the sum of elements at lower indices is equal to …

We've explored how to compute the equilibrium index of an array in Java, focusing on a simple yet efficient approach. By implementing a one-pass solution, we ensured optimal performance while handling possible edge cases.

Jan 5, 2023 · Learn how to find the equilibrium index of an array in Java with step-by-step guidance and examples.

Dec 27, 2024 · Equilibrium Index: In an array, an equilibrium index refers to an index into the array such that the sum of elements at lower indices is equal to the sum of elements at higher indices. For example: A0 = -8 A1= 2 A2 = 5 A3 = 2 A4 = …

Jul 22, 2022 · In this section, we will learn what is equilibrium index in an array and how to find the equilibrium index through a Java program. If the sum of lower indices elements is equal to the sum of higher indices elements is called an equilibrium index of an array. For example, consider the array [-7, 1, 5, 2, -4, 3, 0], where:

In this method we will use single loop to find the equilibrium point in the array. left_sum += arr[i]; int right_sum =0; for(int j=i+1; j<n; j++) .

Array Equilibrium Index For a given array/list (ARR) of size 'N,' find and return the 'Equilibrium Index' of the array/list. Equilibrium Index of an array/list is an index 'i' such that the sum of elements at indices [0 to (i - 1)] is equal to the sum of elements at indices [ (i + 1) to (N-1)].
