character in the entire string repeats the number of times has not been counted, if the number of times to record a repetition, the operation of stitching, will certainly not achieve the desired results. If the string is “ppppp” , if this is done, the output will be "p2p3p4p5" . Therefore, it is necessary to count the number of repetitions of a character in order to perform splicing operations. We only need to count the number of consecutive repetiti
