Example: Finding a pair of numbers in a sorted array that sum up to a target value. /** * Finds a pair of numbers in a sorted array that sum up to a target value. * Uses the two-pointer technique for efficient searching. * * @param {number[]} arr - The sorted array of numbers to search through. * @param {number} target - The target sum to find. * @returns {number[]|null}…
