After the power of 2 is written in binary form, it is easy to find that there is only one 1 in binary, and 1 followed by n 0; therefore, the problem can be converted to determining whether n zeros are followed by 1.
If we subtract this number from 1, we will find that the only one will change to 0, and the original n 0

Originally the small program needs a limit text box input as a number, and retain the effect of up to 2 decimal places, the example found on the internet feel a bit cumbersome, wrote a.
The code is simple, and is mainly handled by the regular group matching feature:
// Check input text, limit only to numbers and numbers with up to
The string $s = ' A, B, C (x, y ("Z", 2, 0)), D, E ';
Split into arrays, the difficulty is C (x, y ("Z", 2, 0)), is a whole.
Desired Result:
Array
' A ',
' B ',
' C (x, y ("Z", 2, 0)) ',
' D ',
' E ');

$s = ' A, B, C (x, y ("Z",
Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... + 1/n ., Even number
First, write a function whose n is an even number:
