簡單的PHP演算法題（待完善…）
只印0
具體個數由輸入的參數n決定
如n=5就列印000000印出一行0101010101010101010101
具體個數由輸入的參數n決定
如test.php?n=3印出010
<?<span>php
</span><span>for</span> (<span>$i</span> = 0; <span>$i</span> < 10; <span>$i</span>++<span>) {
</span><span>for</span> (<span>$j</span> = 0; <span>$j</span> <= <span>$i</span>; <span>$j</span>++<span>) {
</span><span>if</span> (<span>$i</span> % 2 == 0<span>) {
</span><span>echo</span> '0'<span>;
} </span><span>else</span><span> {
</span><span>echo</span> '1'<span>;
}
}
</span><span>echo</span> '<br/>'<span>;
}
</span>?>
『
<?<span>php
</span><span>$i</span> = 0<span>;
</span><span>while</span> (<span>$i</span> < 10<span>) {
</span><span>$j</span> = 0<span>;
</span><span>while</span> (<span>$j</span> <= <span>$i</span><span>) {
</span><span>switch</span> (<span>$i</span> % 2<span>) {
</span><span>case</span> 0:
<span>echo</span> '0'<span>;
</span><span>break</span><span>;
</span><span>case</span> 1:
<span>echo</span> '1'<span>;
</span><span>break</span><span>;
}
</span><span>$j</span>++<span>;
}
</span><span>echo</span> '<br/>'<span>;
</span><span>$i</span>++<span>;
}
</span>?>實作0 01 010 0101…
實作0 01 012 0123 3210 210 10 0
做個計算器
『如test.php?a=2&b=5&operator=cheng輸出10
如test.php?a=6&b=3&operator=chu輸出2
