Execute Commands on an Array
Execute Commands on an Array
You are given an array of integers and a series of commands to process sequentially. There are three types of commands:
- sumfirstk k: Calculate the sum of the first \(k\) elements of the array.
- rotateleft n: Rotate the array to the left by \(n\) positions. When \(n\) exceeds the array's length, perform the rotation modulo the array length.
- sortfirstm m: Sort the first \(m\) elements of the array in non-decreasing order.
After executing a command, output the result on a new line. For the sum command, output the integer sum. For rotate and sort commands, output the updated array as space-separated integers on a single line.
inputFormat
The input is read from standard input (stdin) in the following format:
- The first line contains an integer (n), representing the size of the array.
- The second line contains (n) space-separated integers, the elements of the array.
- The third line contains an integer (q), denoting the number of commands.
- Each of the following (q) lines contains a command in one of these formats:
- sumfirstk k
- rotateleft n
- sortfirstm m
Here, (k), (n), and (m) are positive integers.
outputFormat
For each command, output the result on a separate line to standard output (stdout). If the command is sumfirstk
, output the computed sum. If the command is rotateleft
or sortfirstm
, output the modified array as space-separated integers on one line.## sample
