Answer 1

def paired_shoes(L):
    left = right = 0
    for shoe in L:
        if shoe == 'R':
            right += 1
        if shoe == 'L':
            left += 1

    paired = min(left, right)
    unpaired = max(left, right) - paired

    if left > right:
        shoes = 'left'
    elif right > left:
        shoes = 'right'
    else:
        shoes = None
    return paired, unpaired, shoes


def main():
    n = int(input())
    line = input()
    L = line.split()

    paired, unpaired, shoes = paired_shoes(L)

    print('Paired:', paired)
    print('Unpaired:', unpaired)
    if shoes is not None:
        print('Required', shoes, 'shoes')

main()
