In case when you are looking to filter data with some criteria and put the output in order, use the SORT andFILTERfunctions together: SORT(FILTER(array,criteria_range=criteria), [sort_index], [sort_order], [by_col]) The FILTER function gets an array of values based on the criteria you...
The (binary) heap data structure is an array object that we can view as a nearly complete binary tree. A.length gives the number of elements in the array, and A.heap-size represents how many elements in the heap are stored within array A. PARENT(i) return i / 2 LEFT(i) return 2...
Array b[] is created to help merging the two sorted sections back into a single sorted collection. Here are the performance test results of mergeSort() function using PHP 5.6. Array size: 10000 Average sorting time: 27.802 milliseconds
As a reference, results from an older computer are listed below: Array size: 1000 Average sorting time: 38 milliseconds Number of tests: 1000 Performance: 38.0 O(N) microseconds Performance: 3.813046611743762 O(N*Log2(N)) microseconds Performance: 0.038 O(N*N) microseconds Array size: 2000 ...
