I want to condition the string that I Inputted value ("ello") and variable("hello").
If It found in string("hello"), the return value should be "ello". If not found, the return value should be -1.
But it returned "llll" 4 times because of condition (strs[i] == arrayS[tempVal]).
How can I get the correct answer as mentioned above?
var stres = "hello";
var strs = [...stres];
function searchStr(s) {
let arrayS = [...s];
let tempVal = 0;
let tempStr = [];
while (tempVal < arrayS.length) {
for (let i = 0; i < strs.length; i++) {
if (strs[i] == arrayS[tempVal]) {
tempStr.push(arrayS[tempVal]);
}
}
tempVal++;
}
return tempStr;
}
const res = searchStr("ello");
console.log('res', res)According to you, logic is correct just break the for a loop when the condition is fulfilled. Check below snippet and console output.
var stres = "hello";
var strs = [...stres];
function searchStr(s) {
let arrayS = [...s];
let tempVal = 0;
let tempStr = [];
while (tempVal < arrayS.length) {
for (let i = 0; i < strs.length; i++) {
if (strs[i] == arrayS[tempVal]) {
tempStr.push(arrayS[tempVal]);
break;
}
}
tempVal++;
}
return tempStr;
}
const res = searchStr("ello");
const resS = res.join('');
console.log('res = ', res);
console.log('resS = ', resS);
