逆序数越大,下面的算法优势越明显。原始数据恰好降序排列时效率高于前面的两种算法,但原始数据为升序排列时效率非常低,平均效率略高于前面的count()函数但远低于前面的sort_count()函数。 (4)编写代码,测试三种方法的效率 数据完全升序排列的情况: 运行结果: 测试数据完全降序排列的情况: 运行结果: 测试随机数据的情...
Use np.sort() to sort array values in an ordered sequence in Python. By using this you can sort an N-dimensional array of any data type. This function

numbers = array.array('h', [-2, -1, 0, 1, 2]) # 5个短整型有符号整数的数组(类型码是'h') memv = memoryview(numbers) len(memv) memv_oct = memv.cast('B') # 转换成'B'类型,也就是无符号字符 memv_oct.tolist() memv_oct[5] = 4 ...
A binomial coefficient C(n, k) also gives the number of ways, disregarding order, that k objects can be chosen from among n objects; more formally, the number of k-element subsets (or k-combinations) of an n-element set. Given two numbers n and r, find value of nCr nCr = (n!)...
