128bit,Because 8bit represents a byte, it is 128/8=16 bytes when represented in bytes.Because 4bit represents a hexadecimal, it is 128/4=32 hexadecimal when used in hexadecimal notation.If you print the md5bytes of the above code, you will see a byte array as follows:[-83,-42,-124,-31,-122, 59, 93,-112, 5,-125, 35, 104, 37,-92, 49,-62]There is a total of 16 bytes, and each byte needs to be split into two hexadecimal digits.We first take 59来 demolitio
_get_tasks method genetic builder. In fact, for a series such as range (123), after grouping by chunksize=8, the elements of a total of 16 groups per group are as follows:(Func, (0, 1, 2, 3, 4, 5, 6, 7))(Func, (8, 9, 10, 11, 12, 13, 14, 15))(Func, (16, 17, 18, 19, 20, 21, 22, 23))...(Func, (112, 113, 114, 115, 116, 117, 118, 119))(Func, (120, 121, 122))After grouping, a Mapresult object is defined here: result = Mapresult (Self._cache, chunksize, Len

Number 33rd to 126th (a total of 94) is a character, of which 48th to 57th is 0~9 10 Arabic numerals, 65~90 number 26 uppercase English letters, 97~122 number 26 lowercase English letters, the rest are some punctuation marks, operation symbols and so on.
Note: In the computer's storage unit, an ASCII value occupies one byte (8 bits), and its highes
bonuses, if a row is a null value, the result will be null, as in the following example:
Update Empset salary= (Salary+bonus) *1.1
In this statement, the employee's wages and bonuses will be updated to a new value, but if there is no bonus, i.e. salary + NULL, then the wrong conclusion will be drawn, and the NVL function should be used to exclude the effect of the null value.
So the correct statement is:
Update Empset salary= (SALARY+NVL (bonus,0) *1.1

ES6 extends some of the methods of functions:
1: You can give the function a default parameter
function fn (a,b=7) {
console.log (a,b)
}
fn (1)
When the FN function is invoked, no arguments are passed to B, but because the parameter is set to a default value of 7, the final print a,b value is 1, 7
2: Declare an arrow function, it is anonymous, you can give this anonymous function to pass the parameter
Let A = (a,b,c=90) =>{
console.log (a,b,c)
}
A (1,2)
3: If the function has only
