How to print the sum of series= x/1-x/2+x/3-x/4.....n

Question

plz tell tomorrow is my exam

Answer 1

it can be written as x(1- 1/2 + 1/3 - 1/4 + 1/5 ...)
so U just need to run a loop for accounting that & then multiply that with x in last
double prdct=0;
for (int a=1;a =<n;a++) prdct+=prdct/a;
System.out.println(prdct*x);

👉here , I have taken prdct in double bcz int/int is always an integer in java
//btw can be done directly using math
