Please Help me I am not able To Do It in JAVA

, ,


1 2 3 4 5 (we don’t know the size)

7 6

6 3 5 4 2





10(sum of numbers)





Here we don’t know the number of test cases

And We also don’t know how many numbers to input for each test case

Can anyone provide a Solution for it in JAVA

I was trying to solve it but not able to solve it

same problem with me

You can use getline() to take entire line as input. The code snippet is like-

string s;

If all the numbers are specified to be in a single line then you can take input while you don’t encounter a newline using getchar() function. This function takes input character by character . We then convert this character to number and append it to our number .

Here I have wriiten a code describing the same .

string s;
while (getline(cin,s))

@vijju123 pls help me

@vijju123 ok But how to take number of testcases we don’t know the number of testcase

It will take input only till its available. If no more input is available, it will exit the loop. Execute it yourself and try once.

modification of@vijju123

You dont need the condition to break, while loop exits automatically :stuck_out_tongue:

It isn’t exiting without condition as it still waits for input

No, I tried executing it on compiler before posting here. It very well exits.

Thanks @vijju123 It’s working correctly

If any one can tell that how to do the same thing in JAVA

read about those hasNext() functions etc.
