Find local minima of an array in o(log n) in functional programming.
Use binary search to find the local minima.
Check if the mid element is a local minima, if not, move towards the lower side.
If the mid element is greater than its left element, move towards the left side, else move towards the right side.
Repeat until a local minima is found.
Example: [5, 3, 2, 4, 6, 8, 9] -> local minima is 2.

To find an even length palindrome in a string in O(n), we can use the two-pointer approach.
Initialize two pointers at the center of the string.
Expand the pointers outwards while checking if the characters at both pointers are equal.
If they are not equal, return the previous substring as the even length palindrome.
If the pointers reach the end of the string, return the entire string as the even length palindrome.
Possible values of determinant of matrix A given Avi=Vj for n linear vectors
The possible values of |A| are non-zero as the given vectors are linearly independent

If the given vectors are orthogonal, then |A| is the product of the magnitudes of the vectors

Find the probability of A winning
Find two elements in a sorted array that add up to a given sum in linear time.
Use two pointers, one at the beginning and one at the end of the array.
If the sum of the two pointers is greater than the target, move the right pointer to the left.
If the sum of the two pointers is less than the target, move the left pointer to the right.
Repeat until the sum is found or the pointers meet.
Example: Given [1, 2, 3, 4, 5] and ta
The probability of element at 20th position landing up at 31st position after the first iteration.
The probability depends on the size of the dataset and the algorithm used for iteration.
If the algorithm involves swapping adjacent elements, the probability is higher.
If the dataset is sorted in a way that the element at 20th position is adjacent to the element at 31st position, the probability is 1.
The probability can be...
Expected number of collisions between randomly moving ants on a rod after 30 seconds.
Calculate the probability of two ants colliding at any given time.

Assume that the ants are point masses and collisions are perfectly elastic.
Consider the possibility of multiple ants colliding at the same time.
Simulation can also be used to estimate the expect
Counting permutations where numbers between u and i+1 are less than i for all i in the permutation.
The first number in the permutation must be 1.
For each i in the permutation, all numbers between u and i+1 must be less than i.
Use dynamic programming to count the number of valid permutations.
The answer is (n-1)th Catalan number.
Example: for n=4, the answer is 5.
