Introduction Given an integer array of size n. There are m queries, each query consists of two integers x and y, asking for the maximum value in the range [x, y] of the array. Approach A straightforward method would be to precompute f[i][j] representing the maximum value from index i to j. However, this approach is inefficient. Instead, we can ...
