Description

Given a string S, you are going to shift part of it.
Specifically, a shift on a string is to move all the characters left but the leftmost characters would be move to the rightmost.
For example, a shift on "abcd" would result in "bcda".

This problem ask you implement a function shift(char *start, char *end) that shift a substring of S starting from start to end.

1.      This problem involves three files.

• function.h: Function definition of shift.
• function.c: Function implementation of shift.
• main.c: A driver program to test your implementation.

You will be provided with main.c and function.h, and asked to implement function.c.

• 2.     For OJ submission:

          Step 1. Submit only your function.c into the submission block. (Please choose c compiler) 

  Step 2. Check the results and debug your program if necessary.

Input

The first line is a string S. (length of S<=20)
The second is a integer n. (n<=10)
The next n lines, each contains two integers l and r.(l<=r<=n)
This means that a shift on S[l]S[l+1]...S[r].
If the length of substring is one(l=r), then you should keep the string unchanged.
All these shift must be done in order.

Output

The result string after all n shift operations.

Description

Little Bricks(小磚頭) has a very brilliant calculator,
it can parse the number from the a sentense and sum up all the numbers in the sentense.

One day, he broke the calculator,
but the calculator cannot be bought anymore,
so he ask you to make a new one for him.

ouo.

Hint:
This is a Partial Judge Problem:
0. You will be provided 2 files below: 'main.c', 'function.h'. You should only upload your 'solver' function inside a your '.c' file.
1. The 'main.c' file contains input, output, and function call, the 'function.h' file contains the defination of 'solver' function, and your '.c' file should contain the implement of 'solver' function.
2. You can compile multiple file by command, ex: 'gcc main.c function.h your_code.c', or create a project in your IDE.
3. Remember to include 'function.h'.

#include <stdio.h>

char input[1000010];

int main() {
    int sum = 0;
    int a[maxn];
    int *ptr[maxn];

    for (int i = 0; i < maxn; i++) {
        a[i] = 0;
        ptr[i] = &a[i];
    }

    scanf("%s", input);
    int n = solver(ptr, &sum, input);
    printf("%d", a[0]);
    for (int i = 1; i < n; i++)
        printf(" %d", a[i]);
    printf("\n%d\n", sum);

#ifndef FUNCTION_H

int solver(int **ptr, int *sum, char *s);
#endif

For example, if the sentense is 'Now:12/31,23:59',
then you should parse the 4 numbers: 12, 31, 23, 59 out,
and calculate the sum of these numbers, which is 12+31+23+59=129

The numbers should be separate by a space, after a newline character, output the sum of numbers.
Note that your calculator should be able to handle negative number.

Input

Input contain only 1 line, a string S.

It is guarantee that:
0. 1<= |S| <= 10^6
1. Numbers in S will be in the range [-10^5, 10^5]
2. The ammount of number in S will be in the range [1, 1000]

Output

Output contains 2 lines.

The first line should output all numbers appear in the input string S, separate with a space character,
the next line should be the sum of numbers at the first line.
