Rabbit with Rabbit

Class CLASS5

{

static void Main (string[] args)

{

int TU1 = 1, tu2 = 1; TU1 is the number of rabbits in the penultimate month, TU2 is the number of rabbits in the second month.

int tu=0;//The number of rabbits required for this month.

for (int i = 3; I <=; i++)

{tu = tu1 + tu2;

TU2 = TU1;

TU1 = Tu;

}

Console.WriteLine (TU);

}

}

Age: 6 children lined up, asked how old he was, said he was 2 years younger than the second, asked how old he was, he said he was 2 years younger than the third, and so on, and asked how old he was at 6th, saying he was 16. Q How old is the first child?
Class Class2
{
static void Main (string[] args)
{
int age = 16; Initially, the 6th child age is saved, each cycle will be reduced by 2, representing the age of the 5,4,3,2,1 child respectively.
for (int i = 5; I >= 1; i--)
{
age = age-2;
}
Console.WriteLine (age);
}
}

Class Class4
{
static void Main (string[] args)
{
int count = 1;
for (int i=6;i>=1;i--)
{
Count = (count + 1) * 2;
}
Console.WriteLine (count);
}
}

2. There are three kinds of coins: 1 points, 2 points, 5 points. To combine 1 hairs 5, what are the combinations?

static void Main (string[] args)
{
for (int a=0;a<=15;a++)//a The number of coins representing 1 cents
{
for (int b=0;b<=7;b++)//b The number of coins representing 2 cents
{
for (int c=0;c<=3;c++)//c represents the number of 5 cent coins
{
if (a*1+b*2+c*5 = = 15)
{
Console.WriteLine ("1 cent coins need to" +a+ ", 2 cent of the coins need" +b+ ", 5 cent of the coins need to" +c+ ");
}
}
}
}
}
}
