WebApr 1, 2012 · Sorted by: 27. We count the number of array element reads and writes. To do bubble sort, you need 1 + 4 n accesses (the initial write to the end, then, in the worst case, two reads and two writes to do n swaps). To do the binary search, we need 2 log n + 2 n + 1 ( 2 log n for binary search, then, in the worst case, 2 n to shift the array ... WebApr 29, 2024 · Implementation: Python has built-in binary search functions for both sides: bisect_left() and bisect_right(). The built-in function for Java, Arrays.binarySearch() does not find the left-most insertion point, so it's easier to define our own binary search function. C++ can use the built-in function equal_range(), which returns iterator pointers to the range of …
