55555


I. for (int i = 1; i <= 5; i++) {
for (int j = i; j > 0; j--) {
System.out.print(i);
}
System.out.println();
}

II. for (int i = 0; i < 5; i++) {
for (int j = 0; j < i; j++) {
System.out.print(i);
}
System.out.println();
}

III. for (int i = 1; i < 5; i++) {
for (int j = i; j > 0; j--) {
System.out.print(i);
}
System.out.println();
}

IV. for (int i = 1; i < 6; i++) {
for (int j = 0; j < i; j++) {
System.out.println(i);
}
}

V. for (int i = 0; i < 5; i++) {
for (int j = 0; j < i; j++) {
System.out.print(i+1);
}
System.out.println();
}

Answer 1

The code segment that correctly produces the pattern where the numbers from 1 to 5 are concatenated in ascending order is Option I, which is represented by answer choice C.

Step-by-step explanation:

The student is asking which code segment among the given options will produce the output where the numbers from 1 to 5 are printed in ascending order with each line containing the same digit that corresponds to the line number, with the same amount as the line number. For example, the first line has one '1', the second line has two '2's, and so on until the fifth line has five '5's. The code segment that produces this pattern is:

for (int i = 1; i <= 5; i++) {
for (int j = 0; j < i; j++) {
System.out.print(i);
}
System.out.println();
}

This pattern is represented by option I. The correct answer is Option C.
