944. Delete Columns to Make Sorted in TS

[익명(119.64)]

function minDeletionSize(strs: string[]): number {

let result = 0;

for(let i=0; i<strs[0].length; i++) {

let origin: string= "";

for(let j=0; j<strs.length; j++) {

origin+= strs[j][i];

}

const sorted = [...origin].sort().reduce((a,b)=> a+=b);

if(origin!==sorted) result++;

}

return result;

};

이게 나의 한계입니다 개빡치네
