Question

Design and implement an algorithm that gets as input a list of k integer values N1, N2, …., Nk, as well as a special value SUM. Your algorithm must locate a pair of values in the list N that sum to the value SUM. For example, If your list of values is 3, 8, 13, 2, 17, 18, 10, and the value of SUM is 20, then your algorithm would output either of the two values (2, 18) or (3, 17). If your algorithm cannot find any pair of values that sum to the value of SUM, then it should print the message ‘Sorry there is no such pair of values.’

Answer 1

please give thumbs up, thanks

sample output:

code:

#required funcion
def FindPair(Values,SUM):
hasfound=False;
for i in Values:
for j in Values:
if (i+j ==SUM):
hasfound=True;
a=i;
b=j;
break;
if(hasfound==True):
break;
if(hasfound==True):
print("(",a,",",b,")");
else:
print("Sorry there is no such pair of values.");
  
#main to call FindPair Function
def main():
Values=[3,8,13,2,17,18,10];
SUM=20;
FindPair(Values,SUM);
  
#callinf main functions
main()
