evenly distribute load across workers assumes that num_of_worker <= num_of_load returns load_distribution [][]int, where load_distribution[i][0] is the start index, inclusive, of load for ith worker load_distribution[i][1] is the end index, exclusive, of load for ith worker note that load is zero indexed, i.e., indexed as 0, 1, .

encode version into an integer.
