    max_sum = -float("inf")

    for i in range(4):
    for j in range(4):
        top = arr[i][j]+arr[i][j+1]+arr[i][j+2]
        middle = arr[i+1][j+1]
        bottom = arr[i+2][j]+arr[i+2][j+1]+arr[i+2][j+2]
        total = top + middle + bottom
        max_sum = max(max_sum, total)
return max_sum

    The 2D Array – DS problem tests how you handle multi-dimensional arrays efficiently, especially for pattern extraction like hourglass sums. In the same way, planning an Umrah from Montréal requires organizing multiple elements (flights, hotels, guidance) in a structured way, ensuring everything fits together smoothly for the best experience.The 2D Array – DS problem tests how you handle multi-dimensional arrays efficiently, especially for pattern extraction like hourglass sums.

    This python code worked.

    def hourglassSum(arr):
    # Write your code here
    addn=[] 
    for i in range(4): 
        for j in range(4): 
            top=arr[i][j]+arr[i][j+1]+arr[i][j+2] 
            middle=arr[i+1][j+1] 
            bottom=arr[i+2][j]+arr[i+2][j+1]+arr[i+2][j+2] 
            add=top+bottom+middle 
            addn.append(add)
    return max(addn)

    When working with a 2D array, it’s fascinating how the data structure can be used beyond typical programming logic, even for something creative like aesthetic drawing. Each element in the array can represent a pixel, color value, or pattern detail, allowing intricate designs to emerge from organized data. By mapping numerical values to visual elements, a 2D array can essentially become a digital canvas where shapes, gradients, and patterns take form with precision.

    This approach bridges logic and creativity, transforming mathematical structure into visual art. Whether it’s generating symmetrical patterns, pixel-style illustrations, or experimenting with color combinations, the versatility of a 2D array provides a solid foundation for creating aesthetic drawing projects in a programmatic way.
