• Bounding Box

  14/10/25, 11:23 am

  • A bounding box is a kind of box that is flexible and it kind of wrap around any object. Means if my object is a star then bounding box will create a rectangle around my star object by touching all maximum edges of star. Let’s say if out of 5 edge, 3 edges are bigger and 2 are smaller then bounding box will draw in such a way that it will touch 3 edges.
  • Bounding box is used to identify a shape of object like how big it is or small. Mostly in itext pdf work and in AI object determine.

• Why Array Index Access is O(1)

  14/09/22, 04:23 am

  We know that arrays are stored inside RAM as contiguous memory blocks. So, when we store an array of size 13, let’s say it starts at memory address 2001. If we want to access index 7, we already know that index 0 is located at address 2001, so we can simply calculate the address by adding 2001 + 7 to find where index 7 is stored.

  This is how arrays achieve O(1) time complexity for index-based access using simple mathematical calculations.
