13. Find largest element of given array. code example
Example 1: Write a function that returns the largest element in a list
def return_largest_element(array):
largest = 0
for x in range(0, len(array)):
if(array[x] > largest):
largest = array[x]
return largest
Example 2: find the maximum number from an int Array
---without sort method---
public static int maxValue( int[] n ) {
int max = Integer.MIN_VALUE;
for(int each: n)
if(each > max)
max = each;
return max;
---with sort method---
public static int maxValue( int[] n ) {
Arrays.sort( n );
return n [ n.lenth-1 ];
}
Example 3: kth largest element in an array javascript
function nthlargest(arra,highest){
var x = 0,
y = 0,
z = 0,
temp = 0,
tnum = arra.length,
flag = false,
result = false;
while(x < tnum){
y = x + 1;
if(y < tnum){
for(z = y; z < tnum; z++){
if(arra[x] < arra[z]){
temp = arra[z];
arra[z] = arra[x];
arra[x] = temp;
flag = true;
}else{
continue;
}
}
}
if(flag){
flag = false;
}else{
x++;
if(x === highest){
result = true;
}
}
if(result){
break;
}
}
return (arra[(highest - 1)]);
}
console.log(nthlargest([ 43, 56, 23, 89, 88, 90, 99, 652], 4));
