ternary

Today we will talk about a small knowledge point, a ternary operator. As the name implies, A Trielement operation has three elements. Is the expression roughly composed of condition? Expr1: expr2; A statement adds two expressions. Before the

Title Description:Known three ascending integer arrays A[l], b[m] and c[n]. Find an element in each of the three arrays to minimize the distance between the three triples.The distance definition for triples is: Suppose A[i], b[j], and C[k] is a

This article introduces the content is about TP3.2 in the ternary operator, has a certain reference value, now share to everyone, the need for friends can refer to First look at the manual, Templates can support ternary operators, such as: {

In general we will write this: Copy the Code code as follows: if ($_get[' time ']==null){$time = time ();}Else{$time = $_get[' time '];}Echo $time;If get has time this value is brought into the variable.?> If only simple judgment, according to

(($no%3==1)? $num = 1: ($no%3==2))? $num = 2: ($no%3==0)) $num =3:false; And if ($no 1%3==1) { $num 1=1; }elseif ($no 1%3==2) { $num 1=2; }elseif ($no 1%3==0) { $num 1=3; } Tried, if the display, and the ternary does not show, do not know where the

Introduction to the use of PHP ternary operators, PHP operators When we write PHP, we may if{...} Else{...} Use is the most, but sometimes, we can use C inside the ternary operation, can make the code to reduce a lot! This article describes some of

1, bitwise operatorsThe bitwise operator is used to set the specified bit of an integer number, and if the operand is a string, the ASCII value of the string is manipulated. Type of operation Operator Example Results

From learning PHP to now nearly half a year, today in the Li Tinghui Teacher's course to see a statement like thisClass Factory {static Private $_action = NULL; static public Function setaction () {eval (' self::$_action = new '. Ucfirst (Isset

GeneratorGenerator function: The function body contains the yield keyword, the result of which the function executes is the generator, which is essentially an iterator.deffoo ():Print('First ------>') yield1Print('Second----->')

1. Iterator protocolThe object provides a. Next () method that executes the next method either returning the next item of the program, or getting an exception program, and this iteration can only be done backwards (an inappropriate metaphor: Only

One, lambda expression 1 >>> def add (x, y): #定义一个加法函数 2 return x+y #返回两个参数的相加的值 3 4 >>> z=f (3, 4) 5 >>> print (z) 6 7 #调用加法函数返回7 7 >>> Lambda x,y:x+ Y 8 at 0x0000020f385b86a8> 9 #可以看到lambda是一个 function (function) class object >>> F=lambda x , Y:x+

Ternary operatorsJudging the conditions? (The condition is true when executed): (the condition is false)Contrast memoryvar color= ' Red ';Determine if the color is redif (color=== ' red ') {Console.log (' takeout ');}else {Console.log (' nothing ');}

Ternary operator: The ternary operator, as the first name indicates, requires three operands. Grammar is a condition? Result 1: Results 2;. Here you write the terms on the question mark (?) followed by a colon (:) separated by a result of 1 and

Copy Code code as follows: /** * Ternary Group Triplet * */ Class Triplet { Private $_data = null; Initializing ternary groups Public Function init ($val 1, $val 2, $val 3) { $this->_data[0] = $val 1; $this->_data[1] = $val 2;

This is the question that comes to mind when reviewing lambda expressions today, and it is well known that the ternary operator (?:) in C-Series languages is a very useful statement, About the ternary operator in C Expression 1? Expression 2:

Recently in the project with a nested ternary operation, take it for granted that no problem, no test on the line (the problem is not good), the results were humiliated by colleagues.Conditions? True: false, test condition first, if True then
