1. Sprint activities - standup , burn down and retrospective 2. Git commands 3. Git fetch vs git pull 4. How you will automate script with 3 page + delay in each page is 30 to 100 mins . - partial automation 5. Test ng annotation - Data providers 6. @ test priority 7. DB CRUD operations - create read update delete ( Insert / select/ update/ remove) 8. Delete DB info in automation scripts 9. Perquisites handling in automation ( balance check before placing transfer ) 10 . Get entire text from a webpage and approach to save in Java - I said " list [] " or string.

Solve either one the below coding question you have to move zeros either to end of the array or bring them to beginning of the array. For example, if {14, 0, 5, 2, 0, 3, 0} is the given array, then moving zeros to end of the array will result {14, 5, 2, 3, 0, 0, 0} and bringing zeros to front will result {0, 0, 0, 14, 5, 2, 3}. Solve without using For loop and without using a new blank array/collection. Write a Java program to replace all leading and trailing zeroes in a number without using Replace function. Eg. input - 0001120380.0000 output - 1120380, input - 00012.001200 output - 12.0012
