The difference between logic short-circuit in Java is that logic needs to judge the two conditions on the left and right of the symbol, and the short-circuit If the symbol is true on the left, it will be judged right; if The symbol left is false, then go else.eg.

Developed by BAJDCC.Jprolog is a simple logic problem solving program, which mainly uses the exhaustive method to search the solution space, so the time complexity is affected by the number and le

Written in front of the knowledge:Boolean cast:Except for Nan, null, "", Undefined, 0, function, which are false, the others are true;About conversion, and so I'll write another one, dedicated to string, int, and Boolean conversions.symbols for short-circuit operations: | | ! or with non-the principle of short-circuit operation: when there are more than one expression, the value of the expression on the rig

usually + 5 V; VSS is grounded, Which is 0 V. HighIt is regarded as the logic "1", and the range of the level value is 65% ~ of VDD ~ VDD (or VDD-1.5V ~ VDD) Low LevelIt is regarded as "0" and must not exceed 35% or 0 ~ of the VDD ~ 1.5 V. + 1.5v ~ + 3.5v should be regarded as an uncertain level. Avoid uncertain levels in hardware design. In recent years, with the development of sub-micron technology, the power supply of single chip microco

I. Short Circuit Logic
Short-circuit logic is also called lazy evaluation. It has an interesting feature in well-known Boolean operations: the value is evaluated only when the value is required. For example, conditiona () and conditionb () are true when both conditions are true. Therefore, if conditiona () is false, t

' This is b! ' return 1def C (): print ' This is c! ' Return 1if A () or B () and not C (): print ' ok! 'assume that the and priority is higher than or. Then it should be B again c again a, how directly output a? In fact, this is the case in other languages, just not at the time, which is an interesting feature of the Boolean operator .The Boolean operator has an interesting feature: it only evaluates when a value is required.For example, an expression x and Y requires two variables

Logic and--Short circuit and--Say one of the biggest differences, usually we use the most is short-circuit and to make logical judgments:Short circuit and/or will be judged from left to right, as long as the result can be obtained after the formula no longer Judge .The logic

real fake, fake it for real.So what is the result of using and or not combining together? Example:What is the meaning of this phenomenon, just now I said, the logical operation is from the left to the right of the operation, first count not is not the true,true is true meaning, add a not is not true, that is flase, then add a not, and the fake made the real. So the result of not true is true. Well, now that it's out, it's not going to be the back of the operation. So the direct display of a tru

, the core idea of its operational rules is the short circuit logic.
Expressions are evaluated from left to right, and if the left logical value of OR is true, then all expressions (whether and or or, directly output or left-hand expressions) after or are shorted.
The expression is computed from left to right, and if the left logical value of and is false, then all and expressions are shorted,

1. Short Circuit logicIn a logical operation, if the previous condition can already draw the final conclusion, all subsequent conditions are no longer executed! The logical operation here refers to logic and logic or.We have to understand that the logic and the two conditions are true, it is true, if the first one is f

circuit mechanism in Python:
def a(): print 'this is A!' return 1def b(): print 'this is B!' return 1def c(): print 'this is C!' return 1if a() or b() and not c(): print 'OK!'
If the priority of and is higher than or, shouldn't B be followed by C and then A? How can I output A directly?
In fact, this is also the case in other languages, but I didn't care about it at the time. This is an interesting feature of boolean operators.

The difference between long-path short circuit operationLong road and Operation : Refers to the two sides are integers, is bitwise AND operation, on both sides is a relational operation, is a logical operation.short-circuit and Operation : Refers to from left to right and encounters false to stop the subsequent operation.Long Way or operation |: Refers to a bitwise OR operation when both sides are integers,

Core IdeasThe expression is left-to-right, and if the left logical value of OR is True, then all expressions (whether and or or) that are short-circuited or are directly output or left-hand expressions. The expression is left-to-right, and if the left logical value of and is False, then all the and expressions are shorted, until an or appears, and the output and left expression to the left of or is involved in the next logical operation. If the left of the or is False, or if the left side of and
