WebJul 9, 2024 · Solution 3. If your data is all integral, then this hack can help. It uses a float array to store values. Basically what it does is find the insertion index of a value in between your search value and the integer before it. Since all values are integral, it finds the first occurrence of the search value. WebMethod 2 : By using modified binary search As inputArray is sorted, all duplicate elements are grouped together in adjacent locations. Using modified binary search, find the index of first occurrence of K in inputArray. Let it be leftIndex. Using modified binary search, find the index of last occurrence of K in inputArray. Let it be rightIndex. WebThis solution also does not take advantage of the fact that the input is sorted. Another solution would be to run a binary search on the given sorted array and find the index of any occurrence of the given number target. Since the array is sorted, all occurrences of target will be adjacent. fkj twitter
