ACE CO QUestion
A computer employs RAM chips of 256 bytes and ROM chips of 1024 bytes . If the computer system needs 1 KB of RAM and 1 KB of ROM . then how many address lines are required to access the memory ? My work : num of rams needed of 256 byte = 1024 / 256 =4 num of rom chip ... so total address lines are 4 * log 256 + log 1024 ( i take base of 2) = 4 * 8+ 10 =42 .Is it right approach ?

Maths : what is meant by square free ?
D30={1,2,3,5,6,10,15,30} because D30 is square free so it is boolean algebra and every boolean algebra is distributed and complemented also here square free means no divisor of 30 is square ?

gate : Heap questions
An array of integers of size n can be converted into a heap by adjusting the heaps rooted at each internal node of the complete binary tree starting at the node ⌊(n - 1) /2⌋, and doing this adjustment up to the root node (root node is at index 0) in the order ⌊(n ... n) O (n log log n) O(n log n) I dont get what question meant can ny implemented on following array 1,2,3,4,5 ?
