The question as text
13. A team of four high-school students decided to create a computer program for younger students to help them learn to count and recognize whole numbers from 1 to 25. A table partially completed with numbers from 1 to 25 is given to a younger student. The table consists of five rows and five columns (see Figure 2). The younger student must enter the remaining numbers. Each number from 1 to 25 should be entered only once. Figure 2: Example table partially filled with numbers 24 1 7 14 4 6 22 10 21 3 11 25 9 Each of the four students is responsible for creating several sub-programs that will be included in the program.
