Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

Transformation

Write a program which performs a sequence of commands to a given string $str$. The command is one of:

print a b: print from the a-th character to the b-th character of $str$

reverse a b: reverse from the a-th character to the b-th character of $str$

replace a b p: replace from the a-th character to the b-th character of $str$ with p

Note that the indices of $str$ start with 0.

Input

In the first line, a string $str$ is given. $str$ consists of lowercase letters. In the second line, the number of commands q is given. In the next q lines, each command is given in the above mentioned format.

Output

For each print command, print a string in a line.

Constraints

$1 \leq $ length of $str \leq 1000$

$1 \leq q \leq 100$

$0 \leq a \leq b < $ length of $str$

for replace command, $b - a + 1 = $ length of $p$

Sample Input 1

abcde
3
replace 1 3 xyz
reverse 0 2
print 1 4

Sample Output 1

xaze

Sample Input 2

xyz
3
print 0 2
replace 0 2 abc
print 0 2

Sample Output 2

xyz
abc

Solution in Python3 (judge verdict: Accepted)

s = list(input())
q = int(input())
for i in range(q):
    cmd = [s for s in input().split()]
    cmd[1] = int(cmd[1])
    cmd[2] = int(cmd[2])
    if cmd[0] == "replace":
        c = list(cmd[3])
        h = 0
        for j in range(cmd[1], cmd[2]+1):
            s[j] = c[h]
            h+=1
    elif cmd[0] == "reverse":
        k = cmd[1]
        l = cmd[2]
        while k < l:
            t = s[k]
            s[k] = s[l]
            s[l] = t
            k+=1
            l-=1
    else:
        for m in range(cmd[1], cmd[2]+1):
            print("{}".format(s[m]), end = "")

        print()
