Inputthere are several test cases.In each test case:The first line is a integer N, meaning that the picture is a n * n matrix (3 Next N line is the matrix.The input end with n = 0
Outputfor each test case, output the number of crosses you find in a line.

twelve small rings, and nine 4 Dair antennas depicted by ellipses covering them.
Obviusly, it is desirable to use as few antennas as possible, but still provide coverage for each place of interest. we model the problem as follows: Let A be a rectangular matrix describing the surface of Sweden, where an entry of a either is a point of interest,
Which must be covered by at least one antenna, or empty space. antennas can only be positioned at an entry in. when an antenna is placed at row R and co
The title is as follows: [PHP]
$b? 2:4; echo $d = $a Description strings
Necessary. One or more strings to send to the output. Note: note: Echo () is not actually a function, so you do not need to use parentheses on it. However, if you want to pass one or more parameters to echo (), a parse error occurs when you use parentheses. The Echo () function can be used as echo (' ... ') or as echo ' ... '. The operand type of echo should be string-type. For detailed usage see http://www.w3school.com.c

moved to $ JSON. If it is an array, each element in it is an object. These arrays or objects are directly removed from $ JSON, of course, it will be fixed sometimes (for example, the computing attribute will be converted to a simple data type)

AbstractExcessive object-orientation is a kind of illness that occurs to programmers who use objects over the years. Finally, the original includes poor programming languages and non-essential programming languages, as well as fellow students.
