if i am using these reader then it’s accepted the answer but if i trided the same with scanner it’s not accepting the answer
can anyone please explain me this behavior ?
`func main() {
// your code goes here
reader := bufio.NewReader(os.Stdin)
T, _ := reader.ReadString('\n')
t, _ := strconv.Atoi(strings.TrimSpace(T))
for ; t > 0; t-- {
reader.ReadString('\n')
Arr, _ := reader.ReadString('\n')
arr := strings.Split(strings.TrimSpace(Arr), " ")
ans := findNextGreaterNumber(arr)
fmt.Println(ans)
}
}`
func main() {
f, err := os.Open("input.txt")
if err != nil {
panic(err)
}
scanner := bufio.NewScanner(f)
scanner.Scan()
T := scanner.Text()
t, _ := strconv.Atoi(T)
for ; t > 0; t-- {
scanner.Scan()
scanner.Scan()
Arr := scanner.Text()
arr := strings.Split(Arr, " ")
ans := findNextGreaterNumber(arr)
fmt.Println(ans)
}
}
