从字符串中删除特定匹配[关闭]

Question

I want to remove a particular match of characters from a string.

For example i have strings;

topics-p10-new-model-cars
topics-p20-new-model-cars
topics-p30-new-model-cars
topics-p40-new-model-cars

Then i need the results as,

topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars

That means i want to remove p10-,p20-,etc.. .Those are the page numbers. It may be any number..

How can i do this..? Thanks in advance
