👉 A pyramidwise is a method used in computer science and data structures to store an array of arrays. It allows for efficient manipulation of large arrays by breaking them down into smaller sub-arrays, which can then be stored in a single array without needing to create new sub-arrays each time. For example, consider the following code: ``` int arr[] = {10, 20, 30, 40}; int n = sizeof(arr)/sizeof(arr[0]);
