The binary search begins by comparing the searched element with the middle element of the array. Since ‘mid’ calculate for every iteration or recursion, we divide the array into half and then try to solve the problem. If the searched value is less than the element in the middle of the ...

I suggest you`d better use recursion to achieve it again : int*binary_search_rec(int*array,int*low,int*high,intkey){if(low>high)returnNULL;// No find !int*mid=low+((high-low)>>1);printf("binary_search_rec: mid = %d\n",mid-low);if(key<*mid)returnbinary_search_rec(array,low...

If we classify tree traversals, postorder traversal is one of the traversal techniques which is based on depth-first search traversal. The basic concept for postorder traversal lies in its name itself. Post means "after" (last/finally) and that's why root is being traverse...
recursive functions are usually sub-optimal. Iterating through a data structure's elements involves stepping through the items and returning them to the developer utilizing the data structure, one at a time. Recursion is not suited to stopping abruptly at each step of the process. For this reaso...
It's useful to write a search function in such a way that it returns a negative value indicating the insertion point for the new element if the element is not found. Also, using recursion in a binary search is excessive and unnecessary. And finally, it's a good practice to make the se...
