file contains one test case. each case starts with a line containing two positive integers n (≤ 100), the number of crocodiles, and D, the maximum distance that James coshould jump. then n lines follow, each containing the (x, y) location of a crocodile. note that no two crocodiles are staying at the same position.Output specification: For each test case, print in a line "yes" if James can escape, or "no" if not.Sample input 1: 14 2025 -15-25 288 4929 15-35 -25 2827 -29-8 -28-20 -35-25 -20-13 2

Recently learning JavaScript and jquery, there is just one more MOOC not to see. Combining learning knowledge with other people's code: a code that automatically plays the course:As follows:var main=$ ("body"), var playtime=1;var testtime=1;var fininshed= "This section video, Cumulative viewing time" 100% "; var msg=$ ("Li>Li>var json={"background": "#31e16d", "height": "20px", "padding": "5px", "Top": "700px", "Right": "80px", "position": "Fixed", "C

The topic guarantees that the polynomial has a unique single root within a given interval. output format: Outputs the root of the polynomial within the range in a row, exactly 2 digits after the decimal point.

Therefore, the lookup time complexity of the sequence table is the same as the normal list O (n).Note: This less

Let's start with a simple one: Mooc see above Enter an integer that prints the phonetic alphabet for each number. When the integer is negative, the word "fu" is first output. 10 numbers correspond to the following pinyin:0:ling1:yi2:er3:san4:si5:wu6:liu7:qi8:ba9:jiuInput format:The input gives an integer in a row, such as: 1234 .Tip: integers include negative numbers, 0, and positive numbers.Output format:In a row output this integer correspondi

How long does it take to get the full content of the URL link Web page based on the HTTP1.1 mode?1) because there is no cache locally, it requires a minimum of 1 queries. A maximum of 3 recursive queries are required.Answer: 1 RTTD ~ 3 Rttd.

In the previous article, a process was introduced, and the process of stack changes when calling subroutines was analyzed. This article describes the process of multi-process execution, when a process needs to stop to wait for a certain condition or the CPU to allocate the time slice run out need to switch to another process, when the switch first generates an interrupt, then the CPU will perform the corresponding interrupt processing operation, An important operation, for example, is to protect

Then create a new stack for the subroutine, the assembly instructions are as follows: PUSHL%EBP MOVL%esp,%EBP The PUSHL%ebp instruction pushes the base address of the stack of the keynote program into the stack, and ESP,EBP all points to the next bit of the start of

Myinterrupt.cThe My_time_handler () implementation is called per thousand and the Dispatch flag (my_need_sched) is not 1 o'clock, printing ">>>my_timer_handler hereThe above code is the process scheduling function fault-toler
