Question
You are given a 0-indexed array of distinct integers nums.There is an element in nums that has the lowest value and an element that has the highest value. We call them the minimum and maximum respectively. Your goal is to remove both these elements from the array.A deletion is defined as either removing an element from the front of the array or removing an element from the back of the array.Return the minimum number of deletions it would take to remove both the minimum and maximum element from the array.
Solution
To solve this problem, you need to follow these steps:
-
First, find the minimum and maximum elements in the array. You can do this by iterating through the array once and keeping track of the smallest and largest elements.
-
Next, find the positions of the minimum and maximum elements in the array. Again, you can do this by iterating through the array and noting the index when you encounter the minimum or maximum element.
-
Now, you have four possible scenarios for the positions of the minimum and maximum elements: they could be both at the front, both at the back, one at the front and one at the back, or somewhere in the middle.
-
If both elements are at the front or both are at the back, you only need to perform one deletion to remove them. If one is at the front and one is at the back, you need to perform two deletions. If they are somewhere in the middle, you need to calculate the distance from each element to the nearest end of the array and add those distances together to get the minimum number of deletions.
-
Return the minimum number of deletions.
Here is a Python code snippet that implements these steps:
def min_deletions(nums):
min_val = min(nums)
max_val = max(nums)
min_index = nums.index(min_val)
max_index = nums.index(max_val)
return min(max(min_index, max_index) + 1, len(nums) - min(min_index, max_index))
This function works by first finding the minimum and maximum values and their indices in the array. It then calculates the minimum number of deletions by taking the minimum of two quantities: the maximum index plus one (which corresponds to deleting from the front) and the length of the array minus the minimum index (which corresponds to deleting from the back).

Suppose you have n elements in the array 'a' numbered from 1 to n. It is possible to remove the i-th element of 'a' if the number a[i] and i are relatively co-prime i.e. gcd(a[i],i)=1. After an element is removed, the elements to the right are shifted to the left by one position.An array b with n integers such that 1≤b[i]≤n−i+1 is a removal sequence for the array a if it is possible to remove all elements of a, if you remove the b1-th element, then the b2-th, ..., then the bn-th element. For example, let a=[42,314]:[19,19] is a removal sequence: when you remove the 1-st element of the array, the condition gcd(42,19)=1 holds, and the array becomes [314];when you remove the 1-st element again, the condition gcd(314,19)=1 holds, and the array becomes empty.[2,1] is not a removal sequence: when you try to remove the 2-nd element, the condition gcd(314,2)=1 is false.An array is special if it has at least two removal sequences. For example, the array [1,2,5] is special: it has removal sequences [3,1,1] and [1,2,1]. The array [42,314] is not special: the only removal sequence it has is [1,1].You are given two integers n and m. You have to calculate the number of special arrays a such that the length of a is from 1 to n and each ai is an integer from 1 to m.Input FormatThe first line of the input contains two integers n and m.ConstraintsPrint one integer — the number of special arrays a such that the length of a is from 1 to n and each a[i] is an integer from 1 to m.
