Can anyOne figure this out?

The snail climbs up 7 feet each day and slips back 2 feet each night. How many days will it take the snail to get out of a well with the given depth? Sample Input: 31 Sample Output: 6 Explanation: Let's break down the distance the snail covers each day: Day 1: 7-2=5 Day 2: 5+7-2=10 Day 3: 10+7-2=15 Day 4: 15+7-2=20 Day 5: 20+7-2=25 Day 6: 25+7=32 So, on Day 6 the snail will reach 32 feet and get out of the well at day, without slipping back that night

Abolfazl Abbaspour First take the input from user,Create a variable,Let's name it NoOfFeet, And Initialise it with 0 , Keep increasing it with 5 (7-2=5)Also keep noticing the number of iteration of the loop(By creating a variable and keep incrementing it in loop). If NoOfFeet>well depth, Then get out of loop. And the variable that you've created for noticing the number of iterations,Will be your answer.

Yes, but what exactly do you need help with?

It's giving you the math in the task description. You wrote it out.

This is The Hint 👇🏻 Hint: You can use a loop to calculate the distance the snail covers each day, and break the loop when it reaches the desired distance.

You can try this as well n is the input 7x - 2(x - 1) = n x = (n - 2) / 5 result -> x + (x % 5 != 0)

i = 0; for (; depth > 0;) { i++; depth -= 7 if (depth > 0) { depth += 2 } } console.log(i);
