#使用sort排序，key使用lambda表达式

n = int(input())
method = input()
reversed = True if method=="0" else False

infos =[]
for i in range(n):
    item = input().split()
    name,score = item[0],int(item[1])
    infos.append((name,score))

infos.sort(key=lambda x:x[1],reverse=reversed)
for info in infos:
    print("%s %s" % info)
