Better Answer to f(1 ,2 ,5 ,8 )=52

f(1 ,2 ,5 ,8 )=52:
1=(5-1)*(2/8) 2=(8+2)*(1/5) 3=((8+2)/5)+1 4=2/((5-1)/8) 5=((8-5)+2)*1
6=(8-5)/(1/2) 7=((8-5)*2)+1 8=(5+(8/2))-1 9=(5+(8/2))*1 10=(5+(8/2))+1
11=((8+5)-2)*1 12=((8+5)-2)+1 13=(8+5)*(2-1) 14=(8+5)+(2-1) 15=((8+5)+2)*1
16=(5-1)/(2/8) 17=((5*2)+8)-1 18=((5*2)+8)*1 19=((5*2)+8)+1 20=1/((2/8)/5)
21=(5/(2/8))+1 22=((8*2)+5)+1 23=(8*(5-2))-1 24=(5-2)/(1/8) 25=(8*(5-2))+1
26=(8+5)/(1/2) 27=((8+5)*2)+1 28=((8+5)+1)*2 29=((8-2)*5)-1 30=(8-2)/(1/5)
31=((8-2)*5)+1 32=8*((5-2)+1) 33=((8-1)*5)-2 34=(8*(5-1))+2 35=((8-2)+1)*5
36=8*(5-(1/2)) 37=((8*5)-2)-1 38=((8*5)-2)*1 39=((8*5)-2)+1 40=5/((2-1)/8)
41=(8*5)+(2-1) 42=((8*5)+2)*1 43=((8*5)+2)+1 44=8*(5+(1/2)) 45=(8+(2-1))*5
46=(8*(5+1))-2 47=((8+1)*5)+2 48=8*(5+(2-1)) 49=((8+2)*5)-1 50=5/(1/(8+2))
51=((8+2)*5)+1
