1. 在这个示例中,我们使用了一个额外的变量factorial来存储阶乘的计算结果。在每次循环迭代时,将上一次循环迭代的结果与当前迭代的元素相乘,并将结果赋值给factorial变量。最后输出阶乘的结果。 类图 以下是使用mermaid语法绘制的类图示例: ForLoop- variable- iterable- code_block--+execute() 在这个类图中,我们定义...

The factorial of a non-negative integernis the product of all positive integers less than or equal ton. For example, ifnis5, the return value should be120because1*2*3*4*5is120. Video: Python for Loop Previous Tutorial: Python if...else Statement...
for(range_declaration : range_expression) { //loop statement or block; } range_declaration 标识了一个变量,它会依次被赋予范围中的每个值,在每次迭代时都会赋予一个新值。 range_expression 标识数据源的范围。 如下示例: int values[] { 1, 2, 3, 4, 5, 6, 7, 8, 9}; int total {}; for(...
n_factorial = n_factorial * ii; end 假设我们要计算5的阶乘。如果n为5,for循环控制表达式将会产生行向量[12345]。这种循环将会执行5次,ii值按先后顺序依次为1,2,3,4,5。n_factorial最终的计算结果为1ⅹ2ⅹ3ⅹ4ⅹ5=120。 例 统计分析 执行如下算法: 输入一系列的测量数,计算它们的平均数和标准差。这些...
