A non left recursive and left facotred grammar in which all non-empty rules defining the same non terminal have disjoint first sets, such grammar is called _____________ a) LL(1) b) LR(0) c) LR(1) d) None asnwer given LL(1). but i think bcoz of follow there can be conflict hence none of these should be the answer. Is it right??
Consider a network with five nodes, $N1$ to $N5$, as shown as below. The network uses a Distance Vector Routing protocol. Once the routes have been stabilized, the distance vectors at different nodes are as follows. N1: $(0, 1, 7, 8, 4)$ N2: $(1, 0, 6, 7, 3)$ ... $N1$ in the distance vector of $N3$ ? $3$ $9$ $10$ $\infty$

Consider a complete bipartite graph $k_{m,n}$. For which values of $m$ and $n$ does this, complete graph have a Hamilton circuit $m = 3, n = 2$ $m = 2, n = 3$ $m = n > 2$ $m = n > 3$
If a graph requires $k$ different colours for its proper colouring, then the chromatic number of the graph is 1 k k-1 k/2
