ICSE − Q & A

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

The bodyless loop whose function in the book is given that"It is used to create delay" is actually not taken as a delay for humans as the i9 7980x processor overclocked at 4.6GHz processes it so quickly that hardly i can see any delay but if you actually want a delay u can use Thread.sleep(1000);//here 1000 means 1 second delay time is given inside the brackets is in milli-seconds but whenever u use it dont forget to wrap this function with try-catch block try{ Thread.sleep(1000); } catch(InterruptedException e){ System.ot.println("Technical Problem"); } NOTE:Strictly not for exam purpose

Oh! I have a trick for arrays too. lets assume we have an array named arr then for(i:arr) { System.out.println(i);//Here i have just printed the elements but you can do anything } //Here each time when the loop runs the i contains the next element of the array cell which means if arr[] would be{1,7,10,99,-10} i will have the value 1 in first execution of the for loop then i will have value 7 in next loop and so on.... comment if you liked?

Catch on to fire if you must,sometimes everything needs to burn to the ground so that we may grow.

Could someone please provide me with an example of pure and impure functions that I could write if asked?

I recently realized that 'System.out.println()' is a great example of function overloading.

To get a random integer in the range [min, max), int randomInt(int min, int max) { return Math.floor(min + (Math.random() * (max - min))); } To get a random double in range [min, max): double randomDouble(int min, int max) { return min + (Math.random() * (max - min)); }

ok for patteren like this i ic ics icse we normally use two for loops but there is shor cut . here it is String nm = "icse"; for (int i = 1 ; i<=nm.length();i++) s.o.p(nm.substring(0,1));

Guys all of you must have faced the problem of printing a particular array as it requires the user to type out another for loop which is time consuming tedious and boring
heres a trick but u ll have to import java's utilility package by import java.util.*
just say u wanna print array named arr
type :- System.out.println(Arrays.toString(arr));
the output is like this : [a,b,c,d] try this one out
