The following is a detailed analysis of the differences between the three equal signs () and the two equal signs () in php. For more information, see
First, give a column:For example, a function returns the following results:
1. number greater than 0
2. number smaller than 0
3. number equal to 0 (that is, 0)
4. False (upon failure)
In this case, if you want

Chapter 2: Determine whether the strings are equal and Chapter 2: Determine whether the strings are equal
When comparing string objects, you cannot simply use the comparison operator "=", because the comparison operator compares the addresses of the two strings to see if they are the same. Even if the two strings have the same content, the memory addresses of the two objects are different.

Given a non-empty integer array of size n, find the minimum number of moves required to make all array elements E Qual, where a move is incrementing n -1 elements by 1.Example:Input:[1,2,3]output:3explanation:only three moves is needed (remember each move increments both elements): [+] = gt; [2,3,3] = [3,4,3] = [4,4,4]Think and "algorithm" knowledge unrelated to the simple problem is a bit difficult ah ... First fixed every time to make n-1 element +1, then this n-1 must be the smallest n-

Given a non-empty integer array, find the minimum number of moves required to make all array elements equal, wher E a move is incrementing a selected element by 1 or decrementing a selected element by 1.You may assume the array ' s length are at 10,000.Example:Input: [A] Output:2Explanation:only moves is needed (remember each move increments or decrements one element): [A] = [2,2,3] = [2,2,2]given an array of non-empty integers, find the minimum n
Given a non-empty integer array, find the minimum number of moves required to make all array elements equal, with each move adding 1 or minus 1 to the selected element. You can assume that the array has a maximum length of 10000.For example:Input:[A]Output:2DescriptionOnly two actions are necessary (remember that each step can only add 1 or minus 1 to one of the elements):[2,2,3] = [2,2,2]See: https://leetcode.com/problems/minimum-moves-to-
Integer type values are equal or unequal for analysis, and integer values are not equal
I saw an interview question written by a blogger in the blog. One of the questions is Integer a = 1; Integer B = 1; (a = B )? True: false; at the time, I saw that this was not obvious true. I only knew it when I saw the comment and discussed it. There is a range for the Integer value comparison. Equals is usually used fo
An equal sign is a value assignment. The main problem is the difference between two and three equal signs.The difference between two equal signs and three equal signs in javaScriptIn a word: = convert the type before comparison, = first judge the type, if not the same type, it is directly false.===Indicates constant eq

14:14:09| Category:Javascript|Font SizeSubscription First, = equal ity equals, === identity constant.
=, When the value types on both sides are different, type conversion should be performed first and then comparison should be made.
===, No type conversion is required. The types may vary.
The de
result is true;
If the comparison is: 1 = 2, the left side is the int numeric type, the right side is the int numeric type, the left side is the same type, but the value size is different, the result is false;
In short, "=" only requires the same value; "=" requires the value and type to be equal ^_^

1) compare different types, = to compare "convert to the value of the same type" to see if "value" is equal, = If the type is different, the result is not equal. 2) for comparison of the same type, compare the values directly. The results are the same.
2. for advanced types such as array and object, there is no difference between = and =

The difference between three equal signs () and two equal signs () in php is analyzed. First, give a column. for example, a function will return the following situations: 1. number greater than 0 2. number less than 0 3. number equal to 0 (that is, 0) 4. False (upon failure) if you

What is the difference between = (equal to) and = (all equal to) in Javascript?
Let's take a look at two examples:
Var n = '20140901 ';
If (n = 100)
{
Alert ('equals ');
}
Else
{
Alert ('not equal ');
}
The result is "equal ";
When determining whether a string is the same,
Var n = false;
If (n = 'false ')
