This chapter describes several common PHP math intrinsic functions.
General calculations, we can solve by operators, such as subtraction. Using PHP's mathematical calculation intrinsics can help us solve some of the more complex calculations. The
Title DescriptionThere are n positive integers (n≤20), which are joined in a row to form one of the largest multi-bit integers.For example: n=3, the maximum number of 3 integer 13,312,343 joins is: 34331213Also such as: n=4, 4 integer 7,13,4,246
