      It was indeed a Notorious Coincidence. We apologize for the oversight. The proposer has been banned from the platform.

    Casework: At the position where t[i]!=s[i], we have to definitely apply a single operational and at the position where characters are equal, we can apply no operational or two operations. Consider 1 when t[i]=s[i] otherwise 0. Then count the number of continuous 0 and 1. Let them be c1 and c2 then:

    x=total number of 1 and y=total number of 0

    Case
