This is my code. It shows an error when I create an array of BigInteger and try to assign a value.
package test;
import java.math.*;
import java.la
KEEP IN MIND ALWAYS
All numbers greater then 2147483647 will not be allowed as input because int range is -2147483648 to 2147483647 (Never forget it).
If just in case your output is greater than the limit it will reverse and to its lowest value i.e -2147483648.
I recommend that you use:
coef[a]=new BigInteger("324576565343453456546456546546456456456455643671");
All important functions are in java.lang.Math class and you can perform arithmetic operations by passing a string to it.
