  • Ans. 

    Locate sum of 2 numbers in a linear array (unsorted and sorted) and their complexities

    • For unsorted array, use nested loops to compare each element with every other element until the sum is found

    • For sorted array, use two pointers approach starting from the beginning and end of the array and move them towards each other until the sum is found

    • Complexity for unsorted array is O(n^2) and for sorted array is O(n)
