Q43.
A file system with 300 GByte disk uses a file descriptor with 8 direct block addresses, 1 indirect block address and 1 doubly indirect block address. The size of each disk block is 128 Bytes and the size of each disk block address is 8 Bytes. The maximum possible file size in this file system isQ44.
How many onto (or surjective) functions are there from an n-element ( n \geq 2 ) set to a 2-element set?Q45.
Let A be the 2x2 matrix with elements a_{11}=a_{12}=a_{21}=+1 and a_{22}=-1. Then the eigenvalues of the matrix A^{19} areQ47.
Let G be a weighted graph with edge weights greater than one and G' be the graph constructed by squaring the weights of edges in G. Let T and T' be the minimum spanning trees of G and G', respectively, with total weights t and t'. Which of the following statements is TRUE?Q48.
What is the complement of the language accepted by the NFA shown below? Assume \sum={a} and \varepsilon is the empty string.Q49.
Consider the set of strings on {0,1} in which, every substring of 3 symbols has at most two zeros. For example, 001110 and 011001 are in the language, but 100010 is not. All strings of length less than 3 are also in the language. A partially completed DFA that accepts this language is shown below. The missing arcs in the DFA are
