    All test cases passed!!!

    import re

def replace_symbols(line):
    pattern_1=r'(?<= )&&(?= )'
    pattern_2=r'(?<= )||(?= )'
    substitute_1="and"
    substitute_2="or"
    
    line=re.sub(pattern_1,substitute_1,line)
    line=re.sub(pattern_2,substitute_2,line)
    
    return line


N=int(input())
lines=[input() for _ in range(N)]

for line in lines:
    modified_line=replace_symbols(line)

    Python:

    import re
N = int(input())

content = ""

for _ in range(N):
    s = input() + '\n'
    
    new = re.sub(r" && ", " and ", s)
    new = re.sub(r" \|\| ", " or ", new)
    
    while new != s:
        s = new
        new = re.sub(" && ", " and ", s)
        re.sub(r" \|\| ", " or ", new)
    
    content += s


print(content)
