So we should use a local variable, cilentSessionState, to replace hs.sessionState in the function. And move the set-suite statements down to avoid being changed too early.

测试正确性：
func TESTMaxPow() {
for i := 2; i <= 62; i++ {
b:=Word(i)
p, n := b, 1
for max := (_M) / b; p <= max; {
p *= b
n++
}
pGot,nGot:=maxPow(b)
if p != pGot || n != nGot {
fmt.Errorf("not right!")
}
}
fmt.Println("right")
}
输出: right
