Name	City	Maths	Physics
Nikhil	Jaipur	96	91
Dev	Kochi	95	48
Farid	Chennai	81	32
Asha	Kochi	39	65
Omkar	Kochi	30	91
Meena	Pune	98	90
Kavya	Kochi	98	86

The following pseudocode is executed.

1max = 0
2while (Table 1 has more rows) {
3    Read the first row X in Table 1
4    if (X.Maths > max) { max = X.Maths }
5    Move X to Table 2
6}
7count = 0
8while (Table 2 has more rows) {
9    Read the first row Y in Table 2
10    if (Y.Maths == max) { count = count + 1 }
11    Move Y to Table 3
12}
13Print count
