The first step is to get the hashCode value first.
The second step is to get the hash value according to the hashCode value.
The third step is to get a subscript i from the hash value.
The above code is as follows:
The results are as follows:
The fourth step: traversing the hash bucket of the subscript location.
The fifth step is to make a substitution if the reference is equal or equals equal.

Question:
Input integer a and B, output a/b’s cyclic decimal representation and its loop node length. For example, the decimal number of a=5 b=43 is 0. (116279069767441860465), and the loop node length is 21.
Analysis:
The calculation process of long division
①mod = a%b；
②Decimal = (mod*10) / B;
③mod = （mod*10）%b；
Cycle, step 3, when there is a repeating residue, that is, the loop section appears.
Matters needing attention:
When the two or three steps above are looped, the remainder is zero, that is...

Recently I have been thinking about a thing, just graduated from the moment full of ambition, impatient to finish things, although the quality is poor. But now I don’t want to do anything, even if it’s important. What kind of psychology is this?
1、Add class name:
document.getElementById("myDiv").classList.add("myStyle");
2、Delete class name:
document.getElelmentById("myDiv").classList.remove("myStyle")
3、Check whether there is any CSS fatigue:
myDiv.classList.contains("myCssStyle")
//return true or false
Note: when we add multiple class names, we write them side-by-side and separate them with commas.
