Trailing Zeros 题意分析 Write an algorithm which computes the number of trailing zeros in n factorial. 题意分析 n!末尾含零的个数,这个题关键在于n!有多少5,2*5=10,每凑成一对就多一个0,2的个数远比5多,所以关键是找5. 可以列出几个例子来观察一下: 1 * 2 * 3......
Hi, I am trying to convert a string to a double precision number using str2double. Since my string has leading zeros, i.e., '-0,01298784', when I convert it to double, it comes like -1298784. How can I make sure the leading zeros are still t...
