Write a C program to merge two arrays and then sort the merged array in descending order using quicksort. Write a C program to merge two sorted arrays and then remove duplicate elements from the merged array. Write a C program to merge two arrays using pointer arithmetic and then reverse ...
high: this pointer will point to the index of the greatest element, in a sorted array it will be the last element of the array. low = 0 high = len(arr) - 1 # as python follows 0-indexing Step 2. Check elements at both pointers ...

In above example, I have a 2D arrayabcof integer type. Conceptually you can visualize the above array like this: However the actual representation of this array in memory would be something like this: Pointers & 2D array As we know that the one dimensional array name works as a pointer to...
