ICSE − Q & A

Write the output for the following:
String s="Today is Test" ;
System.out.println(s.indexOf('T'));
System.out.println(s.substring(0,7) + " " +"Holiday");


According to me, the answer should be:Today is Holiday.
But the marking scheme says that it is:Today i Holiday [OR] Today Holiday 

Pls explain which is correct, and WHY TF are two answers being accepted?

Can someone give me the order of logical, relational, and arithmetic operators?

Is function call by reference there in the syllabus? will the icse instruct to write the programmes using only call by reference method?

how many of you have completed and how many just started comp theory?

Write a program to accept numbers in a single dimensional array of size ‘N’. Create another string array of size ‘N-1’ to accept valid mathematical symbols like (+, -, /, %, *…). Calculate and display the result by performing the operations by using the symbols stored in the string array on the values stored in the integer array.

Example: 
 
int Arr[]={1,2,3,4}
String Sym[]={“+”,”/”,"*”} 
The result is 4. ((1+2)/3)*4 

HELP!!

Provide me with some very hard program for a good mental workout and practice.
Please ,
I am providing u with one and u too please provide me some:



Take a 10 elements integer array.
Accept numbers in it from the user which can be negative or positive in the cells.
Now shift the positive numbers on the left side and the negative numbers on the right side in the same sequence as they are been provided in the array by the user.]
Now print the modified array.
Sample Input:{1,-1,2,-2,3,-3,4,-4,5,-5}
Sample Output:{1,2,3,4,5,-1,-2,-3,-4,-5}
(Note that the output can not have the sequence of the positive or negative numbers altered like the output cannot be {2,3,1,5,4,-1,-5,-3,-2,-4})
To make things a bit tough(the way my teacher made it) only 1 array can be used in the entire program.
No problem as it will never come at least in ICSE boards.
Share your tough program problems too please
