‘’’

Example:

input_arr = [
[‘55-29’, ‘55-32’, ‘62-3’, ‘84-38’],
[‘36-84’, ‘23-53’, ‘22-58’, ‘48-15’],
[‘72-80’, ‘48-6’, ‘11-86’, ‘73-23’],
[‘93-51’, ‘55-11’, ‘93-49’, ‘72-10’],
[‘93-66’, ‘71-32’, ‘16-75’, ‘55-9’],
]
ouput_arr = [‘11-86’, ‘16-75’, ‘22-58’, ‘23-53’, ‘36-84’, ‘48-6’, ‘48-15’, ‘55-9’, ‘55-11’, ‘55-29’, ‘55-32’, ‘62-3’, ‘71-32’, ‘72-10’, ‘72-80’, ‘73-23’, ‘84-38’, ‘93-49’, ‘93-51’, ‘93-66’]
input_arr1= [ ‘55-29’, ‘55-32’, ‘62-3’, ‘84-38’,‘36-84’, ‘23-53’, ‘22-58’, ‘48-15’,‘72-80’, ‘48-6’, ‘11-86’, ‘73-23’,‘93-51’, ‘55-11’, ‘93-49’, ‘72-10’,‘93-66’, ‘71-32’, ‘16-75’, ‘55-9’]
