互换琴弦的第一和第二部分
原文:https://www . geesforgeks . org/interchanging-first-second-half-stings/
给定两根弦
和
。通过将一根弦的前半部分和后半部分分别与另一根弦的前半部分和后半部分交换来创建两根新弦。
示例:
Input : fighter
warrior
Output :warhter
figrior
Input :remuneration
day
Output :dration
remuneay
在第一个例子中，战斗机由两部分组成图和图。同样的，战士也是由两部分组成战和瑞奥。互换两根弦的第一部分，创建两根新弦和以及和。类似地，在第二个示例中，报酬的第一部分即 remune 与日的第一部分交换，以创建 dration 和 remuneay 。
