How do you find the sum of a sub array?

Algorithm:

1. Traverse the array from start to end.
2. From every index start another loop from i to the end of array to get all subarray starting from i, keep a variable sum to calculate the sum.
3. For every index in inner loop update sum = sum + array[j]
4. If the sum is equal to the given sum then print the subarray.

How do you find if there is a sub array with sum equal to zero in Java?

Algorithm

1. Declare a Set.
2. Initialize sum to 0.
3. Traverse the array, while i < n (length of the array). Add sum to arr[i] and store it to sum. Check if any of the following conditions is true: sum==0 / arr[ i ]==0 / if Set contains the value of sum. if true, then return true. Add the sum to the Set.
4. Return false.

How do you find continuous sub array whose sum is equal to a given number?

How do you find continuous sub array whose sum is equal to a given number in Java?

1. Iterate through the array.
2. At each element add the next n elements one by one, when the sum equals to the required value print the sub array.

What are sub arrays?

A subarray is a contiguous part of array. An array that is inside another array. For example, consider the array [1, 2, 3, 4], There are 10 non-empty sub-arrays. The subarrays are (1), (2), (3), (4), (1,2), (2,3), (3,4), (1,2,3), (2,3,4) and (1,2,3,4).

What is kadane algorithm?

Kadane’s Algorithm is an iterative dynamic programming algorithm. It calculates the maximum sum subarray ending at a particular position by using the maximum sum subarray ending at the previous position.

What is sub array in Java?

A subarray is a contiguous part of array. An array that is inside another array. For example, consider the array [1, 2, 3, 4], There are 10 non-empty sub-arrays.

What is a sub array solar?

Subarray refers to the solar panels within the subarray of your solar system that is attached to your inverter. To add additional subarray(s) to the existing system details, you can click on ‘ADD SUBARRAY’.

What is maximum sub-array sum?

You are given a one dimensional array that may contain both positive and negative integers, find the sum of contiguous subarray of numbers which has the largest sum. For example, if the given array is {-2, -5, 6, -2, -3, 1, 5, -6}, then the maximum subarray sum is 7 (see highlighted elements).

What is sub-array?

How do you sum an array in Java?

Algorithm

1. Initialize an array arr and a variable sum.
2. Set the value of sum=0.
3. Start a for loop from index 0 to the length of the array – 1.
4. In every iteration, perform sum = sum + arr[i].
5. After the termination of the loop, print the value of the sum.
