Description of Online Test Q1.Start with a given array of integers and an arbitrary initial value x. Calculate the running sum of x plus each array element, from left to right. The running sum must never get below 1. Determine the minimum value of x.

Q2.You are a school student who is attending math class, and your teacher has asked everyone in class to bring a calculator so she could teach her class how to use one. The teacher decides that the first lesson would be, where she would tell a positive number and the students just have to type the exact number into the calculator. But, just as the class is about to begin you find that some of the numbers on the calculator are broken totally while some are working, and only the "multiplication" and "equal to" buttons are working. Since you are a smart kid, you decide that you still want to get to the number that the teacher has just told out loud, as quickly as possible with what you have. Example, if your teacher said the number 60, and you can type 1, 2, 5 only. You will push the buttons: 15 (2 clicks) multiplication (1 click) 2 (1 click) multiplication (1 click) 2 (1 click) equal to (1 click) which requires 7 clicks, but since you are smart you use: 12 (2 clicks), multiplication (1 click), 5 (1 click), equal to (1 click) which is just 5 clicks in all. You want to get to the number as fast as possible, so you have to minimize the number of clicks.
