People who have used an IFRAME know that it is a template, there is an IFRAME, and in the IFRAME, can be nested multiple pages. (The more common problem is that the IFRAME page, often appears when the content display is not full).Remember, by JS to calculate the height, the most important thing is that all the elements wrapped in the inside of the elements, that is, the height of the body, the height of the other elements are present, generally as lon

This example describes how PHP uses inverse polish to calculate wages. Share to everyone for your reference. Specifically as follows:
The general algorithm for converting an ordinary middle-order expression to an inverse Polish expression is:
First you need to allocate 2 stacks, a stack S1 (with a closing symbol) as a temporary storage operator, a stack S2 (empty stack) as an input inverse polish, and the S1 stack can first be placed at the lowest p

Using 6n±1 method to calculate prime number
Any natural number can always be expressed as one of the following forms:
6n,6n+1,6n+2,6n+3,6n+4,6n+5 (n=0,1,2, ...)
Obviously, when the n≥1, 6n,6n+2,6n+3,6n+4 are not prime, only the shape such as 6n+1 and 6n+5 natural numbers are likely to be prime. So, except for 2 and 3, all primes can be represented as 6n±1 (n is the natural number).
According to the above analysis, we can construct the other side sieve

A brief introduction to the algorithm of credit interest in micro-credit
A user carried out a loan of 1000 yuan, the loan period is one months, the final payment on the repayment day is 1060 yuan, that is, the amount of 1000 yuan, one months after the principal is 1000, the interest is 60 yuan! The interest calculation of 2 yuan a day!
And the audit fee of 2 yuan, is still manual audit, artificial loans!
According to this algorithm monthly is 60/1000, this feeling is still very high, a
