Answer 1

function isRotation(s1: string, s2: string): boolean {
    return (s1.length === s2.length) && (s1 + s1).indexOf(s2) !== -1; 
} 
 
let s1: string = "abbc"; 
let s2: string = "cabb"; 
   
console.log(isRotation(s1, s2) ? "yes" : "no");
   
s1 = "abbc"; 
s2 = "bbac"; 
     
console.log(isRotation(s1, s2) ? "yes" : "no");
