Wanton Provocation: Little Rose of Blazing Love

The director asked several questions one after another, and the female guests all answered them one by one.

"Okay, now it's the match point, the last question. The current scores are 5:4:2:2. Let's see if we can separate the second and third places, or let's have overtime. ?” The director deliberately created momentum and looked at the male guests sitting next to him, “Who do you think will win, male guests over there?”

"Teacher Shen, speak first." Director Shen Yanzhou gave the first cue.

Shen Yanzhou raised his eyebrows, "Director, don't you think this question is of little significance?"

"That's right." Ye Jingzhi answered, "I must think that my teammates will win."

Zhang Lin also answered: "That's right."

The director gave up: "Okay, just pretend I didn't ask."

"The last question is a bit challenging~ The question is as follows: On a distant planet, the residents use a very special currency system. In this system, there are only three denominations of coins: 1 yuan, 3 yuan yuan and 5 yuan. Now, an alien visitor wants to buy an item worth 27 yuan, but according to the tradition of the planet, the number of coins used in any transaction must be an odd number.

Excuse me, what is the minimum number of coins that this alien visitor can use and follow tradition to complete this 27 yuan transaction with an odd number of coins? Start answering! "

The answering machine rang in turn.

"The first person to press was Huang Tingsi. Tingsi, what's your answer?"

Huang Tingsi just pressed randomly. She just didn't want to lose and didn't know the answer at all. She looked at Ling Yu on the other side and tried to ask for help.

Ling Yu didn't look at him, his eyes stayed on Jiang Yunning.

Huang Tingsi gritted her teeth and said an answer casually: "Ten coins."

"The answer... is wrong. What a pity." The director said, "Please ask Jing Yi, the second person who pressed the answering machine, to tell me your answer."

Jing Yi hesitated for a moment and guessed: "Seven?"

"The answer... is correct!" the director smiled, "Congratulations to Jing Yi for winning third place."

Jing Yi was a little surprised. She didn't expect that she guessed it right when she answered casually.

"Can you tell me your solution to the problem?"

Jing Yi chuckled and said, "I just guessed at this answer, and I don't know how to solve it."

"You're so lucky." The director smiled and looked at Jiang Yunning, who was lost in thought. "In that case, let's ask Yunning to answer the question."

Jiang Yunning, who was suddenly cueed:...

(?o?o) Just say that the director is an idiot!

[Hahaha, Yunning was suddenly cueed: (???w???)]

[It looks like I was suddenly called when I was fishing at work. 】

[It can be seen that the director likes these two young lovers Cue very much. 】

[No, they are the only real couple in the show, so that’s definitely a cue. 】

Huang Tingsi smiled and said: "Sister Yun Ning may not know it. Director, you are too bullying. If you really tell me how to solve the problem, netizens will think that Sister Yun Ning has peeked at the script."

She added: "Ah, I didn't mean that Yun Ning had read the script, I was just joking."

Jiang Yunning glanced at Huang Tingsi with a cold expression: "To find the minimum number of odd coin combinations to pay 27 yuan, and only 1 yuan, 3 yuan and 5 yuan coins can be used, we can first analyze: Since the total amount is an odd number, and An odd number of coins must be used to pay, which means that we cannot only use even-numbered coins. For example, the odd number of coins cannot be achieved with only a combination of 3 yuan coins, so 1 yuan and 5 yuan coins will play a key role in this problem.

Using a combination of $1 coins and $5 coins is one of the closest ways to achieve your goal while keeping the total number of coins to an odd number. Specifically, use 5 yuan coins to reduce the total number of coins, while using 1 yuan coins to adjust the total amount. "

"One of the most direct combinations is to use 5 5 yuan coins, plus 2 1 yuan coins, so that the total reaches 27 yuan, and a total of 7 coins are used. Since the question requires a minimum number of odd coins, and considering There are restrictions on the amount and coin denomination. In fact, this is the only combination that meets the conditions. Adding 3 yuan coins will only make the total number of coins become an even number, or add unnecessary coins when the total amount is already met, which violates the principle of the least coins. .

因此，最少且满足条件的硬币组合即为使用5枚5元硬币和2枚1元硬币，共7枚硬币。”

Jiang Yunning finished talking about the problem-solving ideas in one breath and looked at Huang Tingsi: "It seems that the explanation is too detailed, so it won't be mistaken for reading the script, right?"

The director smiled: "How is it possible? The problem-solving ideas in the script are completely different from what you said."

After saying that, the director also asked the photographer to give a close-up of the answer: "Look, is it different?"

[Why does Huang Tingsi’s tea always smell like tea? Can't you talk properly? 】

[What is tea gas in tea? Don't drag others into your tea. 】

[Isn’t this tea? Always targeting Jiang Yunning, don't you know that saying these words will easily make people lose money and take justice? 】

【so what? You can't even express your own opinions, Yunfan, don't go too far. 】

[Yunduo, don’t argue with them, just watch the live broadcast with peace of mind. 】
