Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to explain what graphs represent.

Data Structures Theory

Graphs are used to model [1] between objects.

Anumbers

Bsizes

Ccolors

Drelationships

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'numbers' because graphs can have numbers but mainly show connections.

Choosing 'colors' or 'sizes' which are not the main focus of graphs.

Graphs represent relationships between objects, such as connections or links.

2fill in blank

medium

Complete the sentence to describe graph components.

Data Structures Theory

In a graph, points are called [1] and lines connecting them are called edges.

Apaths

Bedges

Cvertices

Dnodes

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing edges with vertices.

Choosing 'paths' which are sequences of edges, not points.

The points in a graph are called vertices (or nodes), and the lines connecting them are edges.

3fill in blank

hard

Fix the error in the explanation about graph edges.

Data Structures Theory

Edges in a graph can be [1] or undirected, showing one-way or two-way connections.

Drag options to blanks, or click blank then click option'

Adirected

Bweighted

Ccolored

Dlabeled

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'weighted' which refers to edge values, not direction.

Choosing 'colored' or 'labeled' which are extra properties, not direction.

Edges can be directed (one-way) or undirected (two-way), indicating the direction of relationships.

4fill in blank

hard

Fill both blanks to complete the explanation of graph use.

Data Structures Theory

Graphs can model [1] relationships and [2] connections between many objects.

Drag options to blanks, or click blank then click option'

Acomplex

Bsimple

Cdirect

Dindirect

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'simple' which underestimates graph capabilities.

Choosing 'direct' which ignores indirect connections.

Graphs are useful because they can model complex and indirect relationships between objects.

5fill in blank

hard

Fill all three blanks to describe graph applications.

Data Structures Theory

Graphs help represent [1] like social networks, [2] like roads, and [3] like molecule structures.

Drag options to blanks, or click blank then click option'

Anetworks

Bpaths

Cstructures

Dnumbers

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'numbers' which is not a typical graph application.

Mixing up 'paths' and 'structures' meanings.

Graphs model networks (social connections), paths (roads), and structures (molecules), showing their wide use.
