OpenCASCADE Curve Length Calculation eryar@163.com Abstract. The natural parametric equations of a curve are parametric equations that represent the curve in terms of a coordinate-independent parameter, generally arc length s, instead of an arbitray

晚饭后朋友发来个问题,正好无事做,动手写了一下 若一个正整数有偶数个不同的真因子,则称该数为幸运数.如4含有2个真因子为 1 和 2 .故4是幸运数.求[2,100]之间的全部幸运数之和. 常规思路 被除数一直除以 1 2 3 ... 直到除以它自身,不过这种比较消耗资源(周知python简洁但效率不高) getf.py def get_Factor(x): """ n 需要求真因数的数(被除数) x x 除数 y rem 余数 quo 商 """
