    javascript Code O(n) 

    function minimumDistances(a) {
   
let mainArr = {}
let result = []
a.map ((ele,index)=> {

  (mainArr[ele] || mainArr[ele] == 0 ? (mainArr[ele] = Math.abs(mainArr[ele] - index) , result.push(Math.abs(mainArr[ele])) ) : mainArr[ele] = index)
             
})

    return  (result.length > 0) ? Math.min(...result):-1;

    }
