Method

intpow(int a, int b)
pow 
if (b > 1)
    return a * pow(a, b - 1);
else
    return a;
intpow(int a, int b, int modulus)
Calculates a^b mod modulus 
int p = 1;
for (int i = 0; i < b; i++) {
    p = (p * a) % modulus;
return p;
intpow(int b, int e)
compute b to the e power (b ** e) 
int a = 1;
for (int i = 0; i < e; i++) {
    a *= b;
return a;
intpow(int base, int exp)
Computes an exponent. 
if (exp < 0) { 
    throw new ArithmeticException("exponent must be non-negative");
if (exp == 0) {
    return 1;
if (exp == 1) {
    return base;
...
intpow(int base, int exp)
pow 
return exp == 0 ? 1 : pow(base, exp - 1) * base;
intpow(int base, int exponent)
Returns the value of the first argument raised to the power of the second argument. 
boolean reciprocal = false;
if (exponent < 0) {
    reciprocal = true;
int result = 1;
while (exponent-- > 0) {
    result *= base;
return reciprocal ? 1 / result : result;
intpow(int base, int power)
pow 
int i, res = 1;
for (i = 0; i < power; i++) {
    res *= base;
return res;
intpow(int i, int pow)
pow 
if (pow == 0 || i == 0)
    return 1;
int r = i;
if (pow > 0) {
    for (int j = 0; j < pow; j++) {
        r *= i;
} else {
...
intpow(int leftOp, int rightOp)
pow 
return (int) Math.pow(leftOp, rightOp);
intpow(int n, int p)
pow 
if (p < 0) {
    throw new ArithmeticException("p cannot be negative. Invalid p: " + p);
if (p == 0)
    return 1;
if (n == 0)
    return 0;
if (n == 1)
