Using another example on S = "abcd", if we have both the replacement operation i = 0, x = "ab", y = "eee", as well as another replacement operation i = 2, x = "ec", y = "ffff", this second operation does nothing because in the original string S[2] = 'c', which doesn'...

grep(pattern, x , ignore.case=FALSE, fixed=FALSE) Search for pattern in x. If fixed =FALSE then pattern is a regular expression. If fixed=TRUE then pattern is a text string. Returns matching indices. grep("A", c("b","A","c"), fixed=TRUE) returns 2 sub(pattern, replacement, x...

C 在Oracle中,调用存储过程时需注意以下几点: 1. **IN参数**可用字面量或变量; 2. **IN OUT/OUT参数**须用变量(因需接收返回值)。 **选项分析**: - **A**:`test('string',50,v_str2)` - 第二个参数`50`为字面量,但对应`b`是IN OUT类型,必须用变量。❌ - **B**:`test(v_str...
