Question

Please give me the answer with proper explanation

package eqnparse
import "strconv"
// STUDENTS: MODIFY THE IMPLEMENTATIONS TO IMPROVE THE BENCHMARK
func (expr Expression) String() (s string) {
for i:= 0; i < len(expr.Numbers)+len(expr.Operators); i++ {
if i%2 == 0 {
// even
s += strconv.ltoa(expr.Numbers[i/2])
} else {
// odd
s += string(expr.Operators[(i-1)/2])
}
}
return
}
func (eqn Equation) String() string {
return eqn.lhs.String() + "=" + eqn.rhs.String()
}
improve the benchmark of above code
