...集合，但是易错且低效
```rust
fn main() {
let a = [10, 20, 30, 40, 50];
let mut index = 0;
while index < 5 {
println!("the index is {}", a[index]);
index = index + 1;
}
}
```
- 使用for循环更简洁紧凑，它可以针对集合中的...
...e, accessList types.AccessList, isContractCreation bool, isHomestead, isEIP2028 bool) (uint64, error) {
// Set the starting gas for the raw transaction
var gas uint64
// Bump the required gas by the amount of transactional data
if len(data) > 0 {
// Zero and non-zero bytes are priced diff...
