Question

In java write a code that returns true or false whenever every number from 1 to 10 appears in the array, but only occurs at most as many times as its value. For example the number 4 must appear in the array at least once but at a maximum of 4 times.
Here is how the code should start. ( Note I'm only asking for what i need to fill in under the boolean method oneThroughTen, not under main.)


public class Numbers{
public static void main(String[] args){
oneThroughTen({1,2,3,4,5,6,7,8,9,10});
oneThroughTen({1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10});
oneThroughTen({1,2,2,3,3,3});
}

public boolean oneThroughTen(int[] nums){
// This is where I'm stuck
}


}

The output of this code should look something like this based on the test cases above.
True
False
False


Any help would greatly be appreciated.

Explanation / Answer

in the boolean function create an array say xyz with size 10 then as a number comes add 1 to the corresponding index ex: if number is 3 xyx[3] = xyz[3] +1 at the see if there is any zero's in the array xyz and if the value in particular index is greater than index if so return false else true.
