we are given two strings: String S of length n and string T of length m for the LCS problem, we have produced the following exponential time recursive program. LCM (S, n, T, m) { if (n == 0||m == 0) return 0 if (S[n] == T[m]) result t = 1 + LCS (S, n - 1, T ... ), LCS (S, n, T, m - 1)); return result; } then the number of times that LCS (S, 1, T, 1) is recursively called equals ________ plz solve?

suppose that in 1000 memory reference there are 40 misses in the first level cache and 20 misses in the second level cache. Assume miss penalty from the L2 cache to memory is 100 cycles the hit time of the L2 cache is 10 clock cycles.the hit time of the L1 cache is ... = (memory reference per instruction) x (miss rate) x (miss penalty) right?? so which miss rate and miss penalty should i put here?

A lexical analyzer uses the following patterns to recognize three tokens $T_1$, $T_2$, and $T_3$ over the alphabet $\{a, b, c\}$. $T_1$: $a?(b \mid c)^*a$ $T_2$: $b?(a \mid c)^*b$ $T_3$: $c?(b \mid a)^*c$ Note that x?' ... prefix. If the string $bbaacabc$ is processed by the analyzer, which one of the following is the sequence of tokens it outputs? $T_1T_2T_3$ $T_1T_1T_3$ $T_2T_1T_3$ $T_3T_3$
