The value of a float type variable is represented using the single-precision $$32$$-bit floating point format of $$IEEE-754$$ standard that uses $$1$$ bit for sign, $$8$$ bits for biased exponent and $$23$$ bits for mantissa. $$A$$ float type variable $$X$$ is assigned the decimal value of $$−14.25.$$ The representation of $$X$$ in hexadecimal notation is

Consider the expression tree shown. Each leaf represents a numerical value, which can either be 0 or 1. Over all possible choices of the values at the leaves, the maximum possible value of the expression represented by the tree is ___.

Consider the tree arcs of a BFS traversal from a source node W in an unweighted, connected, undirected graph. The tree T formed by the tree arcs is a data structure for computing

Suppose a stack implementation supports an instruction REVERSE, which reverses the order of elements on the stack, in addition to the PUSH and POP instructions. Which one of the following statements is TRUE with respect to this modified stack?
