Question
Use java and correctly indent code.

Transcribed Image Text:**Exercise 6**
Find the time complexity of the following Java method in terms of its input:
```java
int bar(int n) {
int result = 1;
for (int i=1; i<n; i++)
for (int j=1; j<i; j++)
result += 2;
return result;
}
```
**Analysis steps:**
a) Identify the problem size and key operation.
b) Compute the number of key operations for different problem sizes. Then generalize to the pattern to define the growth function.
c) Identify the dominant term of the growth function and write down the time complexity in Big O notation.
