A college professor gives several quizzes during the semester, with negative marking. He has become bored of the usual "Best $M$ out of $N$ quizzes" formula to award marks for internal assessment. Instead, each student will be evaluated based on the ... programming, the score the professor needs to award each student. Describe the space and time complexity of your dynamic programming algorithm.

My answer came out to be 13: because when we will compute T(13) { as we are using Dynamic programming , it will have to compute value of T(12),T(11),…...T(2) only once(as it will store it and reuse it) so the stack size will be 1 (for T(13))+11 (for T(12),T(11),…...T(2)) = 12…...(48/4) } will any one help me out

Given a text array $T[1…..n]$ and a pattern array $P[1….m]$ such that T and P are character taken from alphabet $\sum$, $\sum={a,b,c,…..z}$. String matching problem is to find all the occurence of P in T. A pattern occur with shift s in T if $P[1…..m]=T[s+1,…...s+m]$. Consider $T=bacacbaacacac$ $P=cac$ The sum of the value of all s is ________

Main disadvantage of direct mapping is that cache his ratio decreases sharply it two or more frequently used blocks map on to same region. For two level memory hierarchy cache and main memory, WRITE THROUGH results in more write cycles to main emeory then WRITE BACK. is it true or false ? with reasons ? thank you in advance

Why we need to do top-down and bottom-up these 2 approach in dynamic programming? I know bottom-up has better overhead. Then why not bottom up used everywhere? Both have time complexity $O(n^{2})$ right? Plz analysis these two algo for more clearity top-down bottom-up
