Subarray Sum Visualizer with Animation

560. Subarray Sum Equals K

Given an array of integers nums and an integer k, return the total number of subarrays whose sum equals to k.

A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:

Input: nums = [1, 1, 1], k = 2

Output: 2

Example 2:

Input: nums = [1, 2, 3], k = 3

Output: 2

Constraints:

• 1 <=n ums.length <=2 * 10⁴
• -1000 <=n ums[i] <=1 000
• -10⁷ <=k <=1 0⁷

Difficulty: Medium | Topics: Arrays, Hashmaps

Enter the array of integers and a target sum (k). The visualizer will show how many subarrays sum up to k.

Array (comma separated): Target Sum (k):

Java Code: Subarray Sum Equals K

class Solution {
    public int subarraySum(int[] nums, int k) {
        Map<Integer, Integer> map = new HashMap<>();
        map.put(0, 1);
        int count = 0;
        int sum = 0;

        for(int num : nums) {
            sum += num;
            int diff = sum - k;
            if(map.containsKey(diff)) {
                count += map.get(diff);
            }
            map.put(sum, map.getOrDefault(sum, 0) + 1);
        }

        return count;
    }
}
        

LeetCode 75. Sort Colors: Dutch National Flag Problem Visualizer

75. Sort Colors: Dutch National Flag Problem Visualizer

Enter the array (only 0s, 1s, and 2s):

Understanding the Dutch National Flag Problem

The Dutch National Flag problem involves sorting an array containing three distinct values: 0 (red), 1 (white), and 2 (blue). The goal is to sort the array with all elements of the same color adjacent in the order red, white, and blue.

This visualization will help you understand how the sorting algorithm works, step by step:

• i (current): Tracks the current element being processed.
• j (left): Marks the position for the next red (0).
• k (right): Marks the position for the next blue (2).
