The method described in the theory performs binary search for arrays sorted in ascending order. Your task here is to modify the method such that: it allows searching in descending sorted arrays; it returns the first index of a target element from the beginning of the array (the leftmost index...
The first element in the array is at position 0. Our first pass sorts the first two elements (from 0 to top, which is set to 1). For a kSortSublist, the first position of our array is start, so our first pass sorts the two elements at start and start+k. 2. The insertionSort ...
arr = np.array([1, 3, 5, 7]) x = np.searchsorted(arr, [2, 4, 6])print(x) Try it Yourself » The return value is an array: [1 2 3] containing the three indexes where 2, 4, 6 would be inserted in the original array to maintain the order....
Searching a string for finding the location of either a character or group of characters (substring) is a common task. For example: In some situations, usernames and passwords are stored in a single string in which they are separated from each other by a special character such as colon (Ex...

CopyCDAArray found = client.fetch(CDAEntry.class) .where("sys.id[ne]", "nyancat") .all(); Location Did you ever want to query based on a real world location? This is how to do this in java: CopyCDAArray found = client.fetch(CDAEntry.class) ...
Within this wrapper, the sub-queries are enclosed in a queries array. The queries wrapper is used wherever multiple sub-queries can occur. For example: { "query": { "queries": [ { "and-query": ... } ] } } Copy You can compose complex queries consisting of and-queries, or-...
