？

Kotlin代码如下：

fun main() { println("请输入笼子里的头数：") val heads = readLine()!!.toInt() println("请输入笼子里的脚数：") val feet = readLine()!!.toInt()

// 计算鸡和兔的数量
var chicken = (4 * heads - feet) / 2 
var rabbit = heads - chicken 

if (rabbit < 0 || chicken < 0) 
    println("输入有误，无法计算！") 
else 
    println("一共有${heads}只动物，其中鸡有$chicken只，兔有$rabbit只！")

}

的解决程序？

我可以像这样用PHP写一个鸡兔同笼问题的代码：

<?php // Defining the total number of chickens and rabbits $chickens = 10; $rabbits = 9;

// Calculate the total number of animals $total = $chickens + $rabbits;

// Calculate the total number of legs $legs = ($chickens 2) + ($rabbits 4);

// Find the individual number of chickens and rabbits $chickens_individual = ($legs - $rabbits 4) / 2; $rabbits_individual = ($legs - $chickens 2) / 4;

echo "There are $total animals in the cage. \n"; echo "There are $chickens_individual chickens, and $rabbits_individual rabbits. \n"; ?>

以下是一个php实现的鸡兔同笼问题的代码： <?php // 鸡 禽 数量 $j = 10; $t = 6; // 鸡 兔 比例
$jt = 3/2; // 求得兔子数量 $tnum = $j - $j * $jt; // 求得鸡数量 $jnum = $t - $tnum; //打印输出结果 echo "鸡有：".$jnum."只, 兔子有：".$tnum."只"; ?>
