please i need ture answer

the fisrt

Draw PDG

the secound

using Backward static slicing

the third dynamic program slice

Based on the code provided below, solve the following questions: OUW 9 re 1 public String Compute(int [] marks) 201 3 int size-marks.length-1; int pass, fail-e, sumPass=, sumFail-e; 5 int is: 6 while( im -50) { pass+; 11 sumPass++; 12 } 13 else { 15 fail++; : 17 18 19 2 20 21 return "Average of Pass +(sumas5/pass)." Average of fails".(sumFail/fail); 1 14 16 i++; 22) (1): Draw Program Dependency Graph (PDG) for the above shown program. 1 (2): Find Program Slice for the above shown program under the slice criterion
