Debugging Auto Configuration in spring boot application
Debugging Auto Configuration
There are two approaches you can debug and discover more information about auto
configuration.
1. Using Spring Boot Actuator
2. Turning on debug logging
You can switch on debug logging by including a simple property value to
application.properties.
In this example, we are switching on Debug level for all logging from org.springframework
package (and sub packages).
logging.level.org.springframework: DEBUG
When the application is restarted, you will view an auto configuration report printed in the log.

Algorithm to find maximum profit on buying and selling from an array
Class MaximumProfit{
private int maxProfit(int[] prices) {
int profit = 0;
int minimum = 0;
for (int current = 1; current < prices.length; current++) {
int previous = current - 1;
int next = current + 1;
if (prices[previous] > prices[current]) {
minimum = current;
}
if (prices[previous] <= prices[current] && (next == prices.length ||prices[current] > prices[next] )) {
profit += (prices[current] - prices[minimum]);
}
}
return profit;
}
public static void main(String[] args) {
// int[] a = { 7, 1, 5, 3, 6, 4 };
int[] a = { 1, 2, 3, 4, 5 };
// int []a = {7,6,4,3,1};
// int[] a = { 1, 2, 3, 4, 1 };
System.out.println(new MaximumProfit().maxProfit(a));
