Minimum Path Sum in a Grid Using Dynamic Programming
Given a grid of non-negative integers, find the path from the top-left corner to the bottom-right corner that miniimzes the sum of the values along the path. Movement is restricted to only down or right directions.
Example 1:
Input: [[1,3,1],[1,5,1],[4,2,1]]
Output: 7
Explanation: The path 1→3→1→1→1 yields the minimum sum.
Example 2:
Input: [[1 ...

One-Dimensional Array
Creating Arrays
Creating and Initializing One-Dimensional Arrays:
Declaring an array:
int[] myIntArray; // Declares an integer array
Allocating memory (initializing the array):
myIntArray = new int[5]; // Allocates an array that can store 5 integers
Assigning array elements:
myIntArray[0] = 10;
myIntArray[1] = 20;
myIntArray[2] = 30;
