Question
Give a big-Oh characterization in terms of n, of the running time of the
following code fragments
note:
Need a proper proof of the coding.
coding language: java 
 
 
 
A. public static int example1(int[ ] arr) {
int n = arr.length, total = 0;
for (int j=0; j < n; j++)
total += arr[j]:
return total;
}
B. public static int example3(int[ ] arr) {
int n = arr.length, total = 0;
for (int j=0; j<n; j++)
for (int k=0; k<=j; k++)
total += arr[j];
return total;
}
Transcribed Image Text:A. public static int example1(int[ ] arr) { int n = arr.length, total = 0; for (int j=0; j < n; j++) total += arr[j]: return total; } B. public static int example3(int[ ] arr) { int n = arr.length, total = 0; for (int j=0; j<n; j++) for (int k=0; k<=j; k++) total += arr[j]; return total; }
