A challenge that arises in databases is how to summarize data in easy-to-display formats, such as a histogram. A problem in this context is the minimal imbalance problem. Suppose we have an array A containing n numbers, all positive, and another input k. Consider k indices j1, j2, . . . jk that partition the array into k 1 subarrays A[1, j1], A[j1 1, j2], . . . , A[jk 1, n]. The weight w(i) of the ith subarray is the sum of its entries. The imbalance of the partition is

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e. g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?
