We can find the multiples using % operator without any hurdles. But, the problem states that we can't use % operator.Here, we make use of the + operator. We can get the multiples by adding 3 or 5 to the previous multiple. Let's see an example.Input15Output1 2 3 - Multiple ... Read More

Given a binary matrix, we need to find the minimum distance from each cell to the nearest cell that contains 1.Let's see an example.Input0 0 1 1 1 0 0 0 0Output1 1 0 0 0 1 1 1 2The minimum distance is the one that is minimum from current ... Read More

Given an array, we need to find the number of pairs with maximum sum. Let's see an example.Inputarr = [3, 6, 5, 2, 1, 2, 3, 4, 1, 5]Output2 The maximum pair sum is 10. There are 2 pairs with maximum sum. They are (5, 5) and (6, 4).AlgorithmInitialise the ... Read More

Given an array, we have to find the number of pairs whose Bitwise OR is an odd number. Let's see the example.Inputarr = [1, 2]Output1 There is only one pair whose Bitwise OR is an odd number. And the pair is (1, 2).AlgorithmInitialise the array with random numbers.Initialise the count ... Read More
