In this Regex Substitution problem, You are given a text of lines. The text contains && and || symbols. Your task is to modify those symbols to and, or words.

## Problem solution in Python 2 programming.

```import re

n = int(raw_input())
for _ in range(0, n):
line = raw_input()
line = re.sub(r'\ [\&]{2,2}\ ', ' and ', line)
line = re.sub(r'\ [\|]{2,2}\ ', ' or ', line)
line = re.sub(r'\ [\&]{2,2}\ ', ' and ', line)
line = re.sub(r'\ [\|]{2,2}\ ', ' or ', line)
print(line)```

## Problem solution in Python 3 programming.

```import re

ii = int(input())

for i in range(0,ii):
txt = input()
txt = re.sub(r"\ \&\&\ "," and ",txt)
txt = re.sub(r"\ \|\|\ "," or ",txt)
txt = re.sub(r"\ \&\&\ "," and ",txt)
txt = re.sub(r"\ \|\|\ "," or ",txt)
print(txt)```

### Problem solution in pypy programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
import sys
import re

pat = re.compile(r'''(?<= )(&&|\|\|)(?= )''', re.U|re.I|re.M|re.S)

for idx in range(int(raw_input())):
l = raw_input()
if pat.search(l):
print(pat.sub(lambda m: 'and' if m.group(1) =='&&' else 'or', l))
else:
print(l)```

### Problem solution in pypy3 programming.

```import re

for _ in range(int(input())):
str_ = input()
str_ = re.sub(r"(?<= )(&&)(?= )", "and", str_)
print(re.sub(r"(?<= )(\|\|)(?= )", "or", str_))```
