Quick Sort Quick sort is the widely used sorting algorithm that makes n log n comparisons in average case for sorting of an array of n elements. This algorithm follows divide and conquer approach. The algorithm processes the array in the following way. Set the first index of the array to left and loc variable.
Java Implementation of Quick Sort. Ask Question 24. 4 $ begingroup $. Also, even though this is the well known quick sort algorithm, I'd still provide better variable names. Not really a problem here, personal preference. Quick Sort in Java. My Quick sort examination. Quick Sort Implementation C++11.
Set the last index of the array to right variable. Left = 0, loc = 0, en d = n? 1, where n is the length of the array. Start from the right of the array and scan the complete array from right to beginning comparing each element of the array with the element pointed by loc.
Ensure that, aloc is less than aright. If this is the case, then continue with the comparison until right becomes equal to the loc. If aloc aright, then swap the two values.
And go to step 3. Set, loc = right. start from element pointed by left and compare each element in its way with the element pointed by the variable loc. Ensure that aloc aleft. if this is the case, then continue with the comparison until loc becomes equal to left. loc ARRRIGHT SWAP ARRLOC with ARRRIGHT SET LOC = RIGHT END OF IF. Step 5: IF FLAG = 0 Repeat while ARRLOC = ARRLEFT AND LOC!= LEFT SET LEFT = LEFT + 1 END OF LOOP.
Step 6:IF LOC = LEFT SET FLAG = 1 ELSE IF ARRLOC.
