Binary Search on 2D (Two Dimensional) Array
WebFeb 25, 2024 · Binary search is an efficient algorithm for finding an element within a sorted array. The time complexity of the binary search is O (log n). One of the main drawbacks of binary search is that the array must … Web2. 2-Dimensional Array 1. Using Single Pointer In this approach, we simply allocate one large block of memory of size M × N dynamically and assign it to the pointer. Then we can use pointer arithmetic to index the 2D array. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 #include #define M 4 share house wollongong
