Type is an everyday concept to programmers, but its surprisingly difficult to define it succinctly. LeetCode claims that the optimal solution (shown in the "Solution" tab) uses a linear search for the maximum value of the sub-array in each recursive step. Are you sure you want to create this branch? Saving frequency of each number - Create Map
freq that's a Map from x to the number of occurrences of x. The trick to this problem, like many best product of x and y problems, is to find a way to iterate through one of the values in order, then evaluate the other value for each combination and take the best result. This blog is served on the requirements of some peoples. Since the answer can be a huge number, return it modulo 10^9 + 7. This would be a better answer if you explained how the code you provided answers the question. This is the solution I came up with, and it's simple enough. 3rd query: nums = [2,3], k = 6 since 2 XOR 3 XOR 6 = 7. Fledgling software developer; the struggle is a Rational Approximation. You are also given an integer k. Create the maximum number of length k <= m + n from digits of the two numbers.
