Given two arrays that have the same values but in a different order and having no duplicate elements in it, we need to make a second array the same as a first array using the minimum number of swaps. Solution: As discussed, specifying the number of columns in 2-D array is mandatory, so, it will give compile time error. 2) 44:25:47 Register now . In the i i th second | a i | | a i | th person either liked or removed the like (Nikita was lucky in this task and there are no dislikes). I was able to come up with O (n log n) approach where we will sort one of the array say A and for each of the element b in array B, do binary search on sorted array A for value (K-b) . me/free_s. Given two arrays a and b, find all pairs of elements (a1,b1) such that a1 belongs to Array A and b1 belongs to Array B whose sum a1+b1 = k (any integer). In a max heap maximum element is at the root node so whenever we pop from max heap we get the maximum element present in the heap. Otherwise, Bianca grabs the bag.
