Write a method named decimalToBinary that accepts an integer as a parameter and returns an integer whose digits look like that number's representation in binary (base-2). For example, the call of decimalToBinary (43) should return 101011. Constraints: Do not use a string in your solution. Also do not use any built-in base conversion methods like Integer. toString.

In Java:

public static int decimalToBinary (int decimal) {

int binary = 0; / / initial value

int currUnitPlace = 1; / / working location

while (decimal > 0) {

/ / put remainder in current unit place

binary + = currUnitPlace * (decimal%2);

decimal / = 2; / / move to next bit

currUnitPlace * = 10; / / move unit place

}

return binary;

}
