Scanner scn = new Scanner(System.in);↵

scn.nextLine();↵
String str=scn.nextLine();↵
// System.out.println(str+" "+str.length());↵

for(int i=0,j=(str.length()/2);i<(str.length()/2) && j<str.length();i++,j++) {↵
if((str.charAt(i)=='L' && str.charAt(j)=='L') || ( str.charAt(i)=='R' &&  str.charAt(j)=='R'))↵
System.out.println((i+1)+" "+(j+1));↵

else if( str.charAt(i)=='L'&&  str.charAt(j)=='R')  ↵
System.out.println((i+1)+" "+(j+1));↵
